Question

Unless otherwise stated, all objects are located near the Earth's surface, where g = 9.80 m/s2.
A rocket is far away from all planets and stars, so gravity is not a consideration. It is using its rocket engines to accelerate upward with an acceleration a = 9.80 m/s2. On the floor of the main deck is a crate (object with brick pattern) with a mass of 71.0

a) How many forces are acting on the crate? (0,1,2, or 3)

b) Determine the normal force on the crate. N=        N

c) Compare normal force on the crate to the normal force the crate would experience if it were at rest on the surface of the Earth. (short essay)

Explanation / Answer

1) normal force

2) N = m a = 71*9.8 = 695.8

3) They are the same since on earth N - mg = 0 so N = mg
