(6%) Problem 7: Consider the shock absorbers of a 1300 kg car How much energy, in joules, must the shock absorbers dissipate in order to damp a bounce that initially has a speed of 0.95 m/s at the equilibrium position?

Explanation / Answer

Here ,

m = 1300 Kg

v = 0.95 m/s

energy needed to be dissipated = decrease in kinetic energy

energy needed to be dissipated = - 0.50 * 1300 * 0.95^2

energy needed to be dissipated = -586 J

the energy needed to be dissipated is -586 J
