Solve the all parts of given problem:

Problem: The front 1.20 m of a 1,250-kg car is designed as a "crumple zone" that collapses to absorb the shock of a collision.

Part A: If a car traveling 26.0 m/s stops uniformly in 1.20 m, how long does the collision last?

Part B: Use the relation between velocity, acceleration, and distance to find the distance the car travels in order to slow at uniform acceleration to a stop. s

Part C: What is the magnitude of the average force on the car?

Part D: Review how the force during a collision is related to the impulse and change of momentum. Apply this to find the force. N

Part E: What is the magnitude of the acceleration of the car? Express the acceleration as a multiple of the acceleration of gravity. g

I need help to find the magnitude of the average force on the car.
