The trajectory of a cannonball fired from a canon depends on

1) the initial velocity.
2) the angle of projection.
3) the effects of air resistance.
4) all of these.

When air resistance does affect motion, the cannonball doesn't travel
5) as high.
6) as far.
7) as high and as far.

Question 2

Ball A is dropped from rest as ball B is shot out horizontally. Ball A hits the ground

1) before ball B.
2) after ball B.
3) at the same time as ball B.

This is because
4) ball A has less distance to travel.
5) ball B is acted upon by an additional force.
6) both balls fall the same vertical distance with the same acceleration.
