Car B of mass 1200 kg is stationary. Car of mass 20 kg is travelling towards car B at 18 m/s.

At a crash test facility scientists run a car of mass m into a wall at a velocity v. The car comes to rest following the collision. The experiment is repeated several times at the same velocity for several different cars (all of mass m). Given that the mass of the cars and the velocity of the cars are all the same, what aspect of the collision can a car designer try to change to reduce the average force applied to the car (and hence to the occupants of the car)? Question 4Select one: a. Duration of the collision b. Change in momentum of the cars c. Force of the car on the ground d. Momentum of the cars e. The force of the wall on the ground

A 3000 kg truck moving with a velocity of 10 m/s hits a 1000 kg parked car. The impact causes the 1000 kg car to be set in motion at 15 m/s. Assuming that momentum is conserved during the collision, what is the velocity of the truck immediately after the collision?*1 point5 m/s10 m/s17 m/s21 m/sSubmit
