- A space probe, initially at rest, undergoes an internal mechanical malfunction and breaks into three pieces. One piece of mass ml = 48.0 kg travels in the positive x-direction at 12.0 m/s, and a second piece of mass m2 = 62.0 kg travels in the xy-plane at an angle of 105 at 15.0 m/s. The third piece has mass m3 = 112 kg. (a) Sketch a diagram of the situation, labeling the different masses and their velocities, (b) Write the general expression for conservation of momentum in the x- and y-directions in terms of m1, m2, m3, v1, v2 and v3 and the sines and cosines of the angles, taking to be the unknown angle, (c) Calculate the final x-components of the momenta of m1 and m2. (d) Calculate the final y-components of the momenta of m1 and m2. (e) Substitute the known momentum components into the general equations of momentum for the x- and y-directions, along with the known mass m3. (f) Solve the two momentum equations for v3 cos and v3 sin , respectively, and use the identity cos2 + sin2 = 1 to obtain v3. (g) Divide the equation for v3 sin by that for v3 cos to obtain tan , then obtain the angle by taking the inverse tangent of both sides, (h) In general, would three such pieces necessarily have to move in the same plane?

- A tennis ball is flying east towards the wall with a speed of 32.5 m/s. After bounced against the wall, it's flying west with a speed of 26.3 m/s. If the mass of the ball is 0.1 kg, and the time of collision with the wall is 0.051 second, what is the magnitude of force on the wall during this process in unit of Newton?arrow_forwardGrandma has a new car that uses rocket brakes to slow it down. The car has a mass of 850 kg. She starts out by moving forward with a speed of 12.8 m/s. She then applies the rocket brakes, but as the car comes to a stop she forgets to take her foot off the brake pedal and the rocket continues to apply its force. She ends up moving backwards with a speed of 9.32 m/s. The total time the brakes were firing was 6.74 seconds. (a) Find the change in momentum of the car. (b) Using the formula for impulse, calculate how much force the rocket brake was applying to the car on average, including the direction?arrow_forwardA 70.1 kg astronaut is holding a 8.1 kg tool pack while drifting at 10.4 m/s to the right.

- A skater of mass 72.5 kg initially moves in a straight line at a speed of 4.80 m/s. The skater approaches a child of mass 35.0 kg, whom he lifts on his shoulders. Assuming there are no external horizontal forces, what is the skater's final velocity?arrow_forwardb) Two students are watching an action film in which a car drives down a ramp onto the back of a moving lory. Both are moving at high speed, the car slightly faster than the lorry. One student complains that this is impossible because the car would not be able to stop before hitting the cab of the lorry. The car has mass 1250 kg and is moving at a speed of 28.0 m s¯ª. The lorry has mass 3500 kg and a speed of 25.5 m sª. The length of the flat back of the lorry allows a braking distance of 5.0 m. By considering both momentum and energy show that the stunt is possible, provided a minimum force of about 600 N slows the car down. You should support your explanations with calculations. Treat the situation as one in which two objects join together.arrow_forwardAn overnight rainstorm has caused a major roadblock. Three massive rocks of mass ?1=528 kg, ?2=7.00×102 kg, and ?3=311 kg have blocked a busy road. The rocks are lined up from left to right in the order ?1, ?2, and ?3. The city calls a local contractor to use a bulldozer to clear the road. The bulldozer applies a constant force to ?1 in order to slide the rocks off the road. Assuming the road is a flat, frictionless surface and the rocks are all in contact, what force, ?A, must be applied to ?1 to slowly accelerate the group of rocks from the road at 0.100 m/s2? ?A= N Use the value for ?A to find the force, ?12, exerted by ?1 on ?2. ?12= Narrow_forward
