Newton problems

1. Know and understand Newton's laws of motion.

2.  A 10-kg object is pushed on by a 200-N force.  What will be the acceleration?

3.  What is the weight of a 100-kg man?

4.  Would the answer to 3 be different if he was on the moon?  How so?

5.  Consider yourself standing on a scale in an elevator.  The scale reads your weight.  Compared to being at rest, how would the scale reading change (if at all) if the elevator were:

A.  Moving with constant velocity upward

B.  moving with constant velocity downward

C.  Moving with constant acceleration upward

D.  Moving with constant acceleration downward

E.  If the cable snapped (yikes!) and the elevator were falling

6.  Give the name and publication on Newton's major book
