A car moving at 9.5 m/s crashes into a tree and stops in 0.32 s. Part (a) Calculate the magnitude of the force, in newtons, the seatbelt exerts on a passenger in the car to bring him to a halt. The mass of the passenger is 71 kg. Part (b) What would the final velocity be, in meters per second, if the car with the 71-kg passenger had collided with (and stuck to) a car that has a mass equal to and is traveling in the opposite direction and at the same speed?

A car moving at 9.5 m/s crashes into a tree and stops in 0.32 s.
Part (a) Calculate the magnitude of the force, in newtons, the seatbelt exerts on a passenger in the car to bring him to a halt. The mass of the passenger is 71 kg.
Part (b) What would the final velocity be, in meters per second, if the car with the 71-kg passenger had collided with (and stuck to) a car that has a mass equal to and is traveling in the opposite direction and at the same speed?
