I have two separate questions. #1. Do objects in inelastic collisions exert less force?
#2. Using Newton’s second law explain why crumple zones (part of a vehicle design) reduce the force in a collision.

1. They both exert the same amount of force.

2. this delay reduces the force that drivers and passengers feel in a crash.

Explanation:

1. The difference is the type of energy, not force.

2. Newtons second law is---, the velocity is constant.  force = Mass x Acceleration this delay reduces the force that drivers and passengers feel in a crash.

b.transmitters send radio waves, and receivers capture radio waves.

the total distance traveled by the car is

30km + 49km = 79 km .
