# Question: A rocket is far away from all planets and stars

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 75.0 kg (Fig. 4.35).

(a) How many forces are acting on the crate: (1) zero; (2) one; (3) two; (4) three?

(b) Determine the nor-mal force on the crate and compare it to the normal force the crate would experience if it were at rest on the surface of the Earth.
