Question

Unless otherwise stated, all objects are located near the Earth's surface, where = 9.80 .

. 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/s^2 . On the floor of the main deck is a crate (object with brick pattern) with a mass of 71.0kg .
a.How many forces are acting on the crate?
b.Determine the normal force on the crate.
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. (less than 500 words)

Explanation / Answer

Draw a free body diagram about each mass and apply Newton's Laws For m1 summing forces T - m1*g = m1*a so T = m1*g + m1*a Now for m2 m2*g - T = m2*a or T = m2*g -m2*a Now equate both eqns and get m1*g + m1*a = m2*g - m2*a So (m1 + m2)*a = (m2 - m1)*g So a = (m2 - m1)*g/(m1 + m2) The acceleration is the same for both masses
