Sally, who has a mass of 55 kg, is sledding at the park. She places her 9-kg sled at the top of a hill and then runs with a velocity of 3 m/s and jumps on it. What is the combined velocity of Sally and the sled right after she jumps on, in m/s? (Round your answer to one decimal place if necessary.

A 15 g bullet is shot vertically into an 2.10 kg block and does not exit. The block lifts upward 8.0 mm (see the figure). How fast was the the bullet going before it collided with the block? Ignore the effects of air resistance. Give your answer in m/s to three significant figures.
a)If Olaf catches the ball, with what speed vf do Olaf and the ball move afterward? Express your answer numerically in meters per second. b) If the ball hits Olaf and bounces off his chest horizontally at 8.30 m/sm/s in the opposite direction, what is his speed vf after the collision? Express your answer numerically in meters per second.
Big Boris (90kg) skates backward, 1.0 meter ahead of small skater Sofia (45 kg) , holding her hand as they travel 3.0 "/s . At the 30-second mark, Boris starts pulling Sofia past him, so that by 32.0 s she is 1.0 m ahead of him. During that move, what was Sofia's average velocity, relative to Boris? -0.5 m/s -2.0 m/s +2.0 m/s -1.0 m/s +0.5 m/s +1.0 m/s
The Hulk (200kg of pure angry muscle)collides head-on with a truck (2500kg). If the Hulk was running at 10.0m/s and the truck was moving at 15.0 m/s in the opposite direction, after they stick together, what is their speed (in m/s)? Either the Hulk or the truck needs a negative initial velocity.
Lionel Messi scores a last second goal and, in celebration, runs as fast as he can, drops to his knees and slides along the wet grass of the field. Messi has been clocked (this is true) at a top speed of 9 meters per second in a game. Let's take this as his maximum velocity and the speed he is moving right before he drops down to slide.Take Messi's mass to be 72 kilograms, and take the coefficient of kinetic friction between skin and wet grass to be 0.4How far does Messi slide?
The mass of a regulation tennis ball is 57 g (although it can vary slightly), and tests have shown that the ball is in contact with the tennis racket for 30 ms. (This number can also vary, depending on the racket and swing.) We shall assume a 30.0 ms contact time. One of the fastest-known served tennis balls was served by “Big Bill” Tilden in 1931, and its speed was measured to be 73 m/s. (a) What impulse and what total force did Big Bill exert on the tennis ball in his record serve? (b) If Big Bill’s opponent returned his serve with a speed of 55 m/s, what total force and what impulse did he exert on the ball, assuming only horizontal motion?
A 1500kg sport car is moving westbound at 20m/s on a level road when it collided with a 4000kg truck driving east on the same road at 15m/s. The two vehicles remain locked together after the collision. a)what are is the magnitude of the velocity of the two vehicles just after the collision?
A 2.00 kg ball falls off a 200.00 cm high wall. If the time during the collision is 0.050 seconds, what is the force of impact caused by the ground on the ball? USE SIGNIFICANT FIGURES in the answer!
During a car collision, the knee, thighbone, and hip can sustain a force no greater than 4000 NN. Forces that exceed this amount could cause dislocations or fractures. Assume that in a collision a knee stops when it hits the car's dashboard. Also assume that the mass of the body parts stopped by the knee is about 20% of the total body mass. The person with a mass of 90 kgkg is initially traveling at 18 m/sm/s (40 mi/hmi/h). What minimum stopping time interval in needed to avoid injury to the knee? What is the minimum stopping distance?
A guy running drops from a tower to the ground. The height of the tower is 8 m. (a) How fast is the person going when he hits the ground (assuming no air resistance)? (b) If the person's mass is 65 kg, what is his momentum when he hits the ground? (c) If he lands and bends his knees, he comes to rest in 0.2 sec. What force is being exerted on his legs to stop him?
The mass of a regulation tennis ball is 57 g (although it can vary slightly), and tests have shown that the ball is in contact with the tennis racket for 30 ms.(This number can also vary, depending on the racket and swing.) We shall assume a 30.0 ms contact time. One of the fastest-known served tennis balls was served by “Big Bill” Tilden in 1931, and its speed was measured to be 73 m/s. Suppose that the positive direction of the x-axis is along the direction of motion of the ball after Big Bill's hit. What is the x-component of the force exerted by Big Bill on the tennis ball in his record serve? If Big Bill's opponent returned his serve with a speed of 55 m/s what is the x-component of the force he exerted on the ball, assuming only horizontal motion?
Yesterday you saw in the news that the Giant Asian Murder Hornet has migrated to North America. You didn't think much about it until today when one of those suckers crashed at high speed into the screen door at the back of your house (splat!). The thing hit the door so hard that the door swung shut! We will assume that GAMH had a mass of m = 0.064 kg and was moving with an amazing velocity of v = 6.4 meters/second. The GAMH splatted a distance d = 0.68 meters from the hinge. The door itself can be treated as a rod of mass M = 1.089 kg with a length of L = 0.92 meters rotating about its end. Determine all the following:a) Write the FORMULA for the moment of inertia of the door without the hornet: I = kg m2b) Write the FORMULA for the moment of inertia of the door with the hornet: I = kg m2c) Determine the angular momentum of the hornet before it collides with the door Lhornet = kg m2/sd) Determine the angular velocity of the hornet-stained door after the collision ?2 = rad/sece)…
