A 0.4 kg block rests on a desk. the coefficient of static friction is 0.2. You push the side of the block but do not have a spring scale to measure the force you use. the block does not move.

The diagram shows a motion map Which best describes the motion of the object between 1 and 4 seconds toata • The object has decreasing acceleration and increasing velocity The object has positive acceleration and eventually stops The object has

Decide which of newtons laws each situation shows. A grasshopper leaping into the air comes back down to the ground instead of continuing off into space. As you swim you move forward by pushing water back with your arms.

In otherwise empty space is a system of 4 particles, each of the same mass. The accelerations of the particles are as follows: a1 = ˆi a a2 = ˆj a 2 a3 = - (ˆi + ˆj) (2 a) a4 = (ˆi - ˆj) (3 a), where a > 0 is a constant.
