next Monday as a handwritten hardcopy at period start.
A 100 g ball is held in a person’s hand. The person throws the ball straight up in the air.
During the throw, the person accelerates their hand upward from
rest to an upward velocity of 7.5
m/s after an upward displacement of 75 cm. Assume constant acceleration of the hand during the
(10 pts) Draw an accurate free body diagram (FBD) for the ball
during the throw showing the ball,
all forces acting on the ball paying attention to their relative magnitudes, the direction of the
acceleration of the ball and, using the forces you drew, the direction of the net force acting on
the ball. Include a coordinate system and state what reference frame you will be using.
(10 pts) What is the upward acceleration of the ball during the throw?
C. (10 pts) Write down the magnitudes of all forces acting on
the ball during the upward throw.
What is the agent for each of these forces? What
