A 1000kg 'Smart Car' is stopped at an intersection. A large 4000kg SUV approaches from behind with a velocity of 15m/s and finds itself on a sheet of ice, unable to slow down or change direction. The cars collide in a perfectly inelastic collision which lasts 0.1 seconds. a. Calculate the average force and acceleration that each car experiences during the collision. b. Calculate the average net force that would be exerted on a driver of mass 50 kg if he/she was in either car. Compare these forces to weight, e.g., twice as large as gravity.

Question

Transcribed Image Text:A 1000kg "Smart Car' is stopped at an intersection. A large 4000kg SUV approaches from behind with a velocity
of 15m/s and finds itself on a sheet of ice, unable to slow down or change direction. The cars collide in a perfectly
inelastic collision which lasts 0.1 seconds.
a. Calculate the average force and acceleration that each car experiences during the collision.
b. Calculate the average net force that would be exerted on a driver of mass 50 kg if he/she was in either car.
Compare these forces to weight, e.g., twice as large as gravity.
