Mass, Weight, Friction

A scientist pilot is measuring a meteor he found. He measured it to have 30 kg for its mass. The asteroid is sitting on a scale that measures Newtons. How many Newtons would the scale read? ( F = m*a)

The scientist pilot also happens to be flying 300 meters above the ground in his airplane laboratory. As he forgot he was flying an airplane still in the air, he accidentally dropped the asteroid out of the plane as he rushed to the cockpit! How many m/s will it be going when it hits the ground? (2 sig figs)

Suppose the dropped asterioid was going 77 m/s before it hit the ground. How long will it take to reach the ground from being dropped from the plane? (V_f = V_i + a*t) _ m/s
