A golf ball of mass 0.050 kg is at rest on the tee and has a velocity of immediately after being struck. If the club and ball were in contact for what is the average force exerted on the ball?

Water flows through a garden hose which is attached to a nozzle. the water flows through hose with a speed of 2.19 m/s and through the nozzle with a speed of 19.8 m/s. calculate the maximum height (in m) to which water could be squirted if it emerges from the nozzle and emerges with the nozzle removed.
