An 80.0 kg skydiver is falling straight down with a terminal velocity of 60.0 m/s. What is the magnitude of the drag force on the skydiver? You can take g = 10 m/s2.

A ball rolls horizontally off the edge of a cliff that is 10 m high. It strikes the ground at a distance 4.0 m away from the edge of the bottom of the cliff. About how long is the ball in the air? Take g = 10 m/s2

Two footballs A and B are kicked from a field line at an angle of 45° from the horizontal. Ball A has initial speed v, and ball B has initial speed v/2. The launch angles are the same. If ball A travels a distance d before reaching its maximum height, then the distance travelled by ball B before reaching its maximum height is:

A block of mass m rests on a frictionless inclined plane that makes an angle
