Answer #1

Mass was not provided ,please substitute m and get your answer from the F=7.306m

From Kinematic equation

when car comes to stop ,final velocity is zero i.e V=0.since the car is decelerating acceleration is negative.

The Braking force required to stop the car is

Here Mass of car was not given ,for example i am considering mass of car on average m=1500 kg

A new car, car 1, has a spring loaded rear bumper with a force constant of 8.4x105 N/m. While car 1 is parked, a second vehicle, car 2 (with mass of 1.5x103 kg), travels at a constant speed of 18 km/h, hitting car 1 in the rear bumper.             a)        Calculate the kinetic energy of car 2. b)        Calculate the distance that car 1’s bumper will compress if car 2 comes to a complete stop after striking it.
