A mass m1 = 1.0kg weighs one -sixth as much on the surface of the moon as on the earth. calculate the mass, m2 of the moon .the radius of the moon is 1.738×10^6m.

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
