An energy-absorbing car bumper with its springs initially undeformed has an equivalent spring constant of 3000 lb/in.

Question:

An energy-absorbing car bumper with its springs initially undeformed has an equivalent spring constant of 3000 lb/in. If the 2500-lb car approaches a massive wall with a speed of 5 mi/hr, determine

(a) The velocity v of the car as a function of time during contact with the wall, where t = 0 is the beginning of the impact,

(b) The maximum deflection x_max of the bumper.
