Question
An pickup truck with mass 1.72 x103 kg is traveling eastbound at +15.2 m/s, while a compact car with mass 9.12 x102 kg is traveling westbound at -15.2 m/s. The vehicles collide head-on, becoming entangled.
(a)the speed of the entangled vehicles after the collision is 4.7 m/s
(b)the change in the velocity of each vehicle are:
| Δvtruck | = -10.5 m/s |
| Δvcar | = 19.9 m/s |
(c) The change in the kinetic energy of the system consisting of both vehicles is -274978.2 J
Use the values to help you work this exercise. Suppose the same two vehicles are both traveling eastward, the compact car leading the pickup truck. The driver of the compact car slams on the brakes suddenly, slowing the vehicle to 5.78 m/s. If the pickup truck traveling at 18.7 m/s crashes into the compact car, find the following.
(a) the speed of the system right after the collision, assuming the two vehicles become entangled
(b) Find the change in the velocity for both vehicles
(c) the change in kinetic energy of the system, from the instant before impact (when the compact car is traveling at 5.78 m/s) to the instant right after the collision
