Question

How much energy must the shock absorbers of a 1200-kg car dissipate in order to damp a bounce that initially has a velocity of 0. 800 m/s at the equilibrium position

Answer 1

Answer:

384 joule

Explanation:

mass(m) = 1200 kg,velocity(v) = 0.800m/s, Kinetic Energy(KE) = ? We know that, KE = 1/2 m× v×v, = 1/2× 1200×0.800×0.800 = 600× 0.64 = 384 joule
