Question

one hazard of space travel is debris left by previous mission. there are several thousand masses large enough to detect by radar orbiting the earth,but there are far greater numbers of very small mass such as flakes of paints calculate the force exerted by a 0.160 mg chip of paint that strikes a space shuttle window at a relative speed of 3.00× 10^3m/s and sticks given the collision lasts 6.00× 10×-^8s such a collision chipped the window of the I'll fated challenger in June 1983 causing $50,000 of demage

Explanation / Answer

In physics, this scenario describes IMPULSE ... F x t    also known as the change in momentum...(final momentum = 0)

Momentum = m x v

                   = 0.160 mg x 1kg/1000mg    x 3 x 10^3 m/s =   .048 kg-m/s   = 0.48 N-s

F x t = 0.48 n-s

F = 0.48 N-s / (6x 10^-8 s) = 8.00 x 10^6 N
