4. On a day with heavy rainfall, when the roads were slippery, the two cars, A and B, collided at right angles at the intersection. During the collision, the cars became entangled (AB) and moved off together to bump to a huge old tree. Calculate the velocity (km/h) of car B just before collision with car A at the intersection. Right after bumping with the tree, determine the new velocity of the "entangled" cars. Also, compute for the percent energy lost from the cars after the two collisions occurred. Neglect the geometry of the cars before and after collision. Other details are tabulated below: Parameter Mass of car A, m₁ (kg) Mass of car B, mB (kg) Velocity of car A just before collision with car B, VA1 (km/h) Velocity of car B just before collision with car A, VB1 (km/h) Coefficient of restitution between cars A and B, CAB Coefficient of restitution between the entangled cars (AB) and the tree (C), eABC Value (with respect to your student number) 1290 1630 55, 1 unknown, → unknown…
The track for this racing event was designed so that riders jump off the slope at 35°, from a height of 2.25 m. During a race it was observed that the rider shown in Figure below remained in mid air for 0.75 s. Determine the speed at which he was traveling off the ramp, the horizontal distance he travels before striking the ground, and the maximum height he attains. Neglect the size of the bike and rider.

UBC Engin A trebuchet uses a falling counterweight to launch a projectile. It can be thought of as a machine that converts the gravitational potential energy of the counterweight into kinetic and gravitational potential energy of the projectile. The counterweight has a mass of 100kg and drops 3m. The projectile has a mass of 3kg, and starts on the ground. When it leaves the sling, it has a height of 4m speed of 30. m If the average power used in lifting the counterweight is 48W, find the time it takes to lift it from the ground to its full height. tlifting If the projectile goes from rest to its maximum speed in 1.5s. find the average power used in launching the projectile in this time period. Pprojectile Find the efficiency of the trebuchet when it launches. Efficiency % W
Gayle runs at a speed of 4.10 m/s and dives on a sled, initially at rest on the top of a frictionless snow-covered hill. After she has descended a vertical distance of 5.00 m, her brother, who is initially at rest, hops on her back and together they continue down the hill. What is their speed at the bottom of the hill if the total vertical drop is 15.0 m? Gayle's mass is 46.5 kg, the sled has a mass of 5.25 kg and her brother has a mass of 30.0 kg.
