Question: Object A weighs twice as much as object B at the same spot on the earth. Would the same be true at a given spot

  1. Object A weighs twice as much as object B at the same spot on the earth. Would the same be true at a given spot on Mars? Account for your answer.

2.

An elevator, complete with contents, has a mass of 2000.0 kg. For each of the two situations described in a) and b) below, do the following.

Draw a free-body diagram showing the correct relative lengths of theTand theFgvectors.

Determine the value ofT(the tension in the elevator cable).

State the value of the real weight and the apparent weight in each case.

  • a. The elevator is moving up at a constant velocity of 2.0 m/s.
  • b. The elevator is moving up at a constant acceleration of 1.0 m/s2.
