A ball is thrown into the air with some initial velocity.  It rises to a maximum height, turns around and falls to the Earth.  Which statement describes the acceleration vector during this motion?  Assume a coordinate system where up is positive.

On the Moon, the acceleration due to gravity is 1.6 m/s2 and there is no atmospheric drag.  During Apollo 14, Alan Shepherd hit a golf ball on the Moon.  If he hit the ball at an angle of 20° with an initial velocity of 35 m/s, find the total time the ball was above the ground.  Assume it landed at the same height as it was hit.

An object is suspended by two strings that each make an angle of 45 degrees from horizontal.  If the tension in each string is 100N, what is the weight of the object?

A coffee filter is dropped from rest and reaches a terminal velocity of 1 m/s.  The cross section area of the filter is .017 m2 and it has a mass of 0.00084 kg.  What is the drag coefficient of the filter?  The density of air is 1.2 kg/m3.  The drag force is proportional to v2.
