A 2000 kg car strikes a wall at 15 m/s and comes to a stop in .15 seconds. With how much force did the car strike the wall? Please show all work.
A 5,000 kg truck traveling at 50 m/s encounters a wall and comes to a stop as it crashes into the wall. The force of the crash was 60,000 N. How long was the crash?
A 2000 kg car is traveling at 45 m/s. A force of 4000 N is applied to the breaks of the car as it slows down to 15 m/s. How far does the car travel as it slows down? please show all math steps and how you set up the equations. Thanks!
A 0.06-kg lead bullet traveling 151 m/s strikes an armor plate and comes to a stop. If all of the bullet's energy is converted to heat that it alone absorbs, what is its temperature change?
A 0.07-kg lead bullet traveling 170 m/s strikes an armor plate and comes to a stop. If all of the bullet's energy is converted to heat that it alone absorbs, what is its temperature change?

The mass of rain per second that strikesthe roof of the car is 0.060 kg/s. Assuming that rain comes to rest upon striking the car, find the average force exerted by the rain on the...
) A 2000 kg truck is going 20 m/s collides with a brick wall bringing it to a stop. The truck is totaled, but the wall is fairly undamaged. If the collision lasts 100ms, find the average force exerted on the truck by the brick wall. How does this compare to the force that the truck exerts on the wall?
1. A 12,000 kg railroad car, intially traveling at 1.6 m/s, strikes three identical and connected railroad cars, initially at rest. The track is horizontal and frictionless. After the collision, all four cars move together at the same velocity. A. Determine the final speed of the cars. (0.4 m/s). B. Assuming the collision took 1.5 seconds, calculate the average force of collision. C. How much non-conservative work was done during the collision? (-11500 J)
