1. if a block is moving to the left at a constantvelocity, what can one conclude?

a) there is exactly one force applied to the block

b) the net force applied tot the block is directed to theleft

c) the net force applied to the block is zero

d) there must be no forces at all applied to the block

2. A block of mass 2 kg is acted upon by two forces: 3N(directed to the left) and 4N (directed to the right) What can yousay about the block's motion?

a) it must be moving to the left

b) it must be moving to the right

c) it must be at rest

d) it could be moving to the left, moving to the right or beinstantaneously at rest

3. A massive block is being pulled along a horizontalfrictionless surface by a constant horizontal force. The block mustbe...

a) continuosly changing direction

b) moving at constant velocity

c) movint with constant nonzero acceleration

d) moving with continuosly increasing acceleration
