vector quantities

A ball of mass M is thrown vertically upward with an initial speed of vo. It experiences a force
of air resistance given by F = –kv, where k is a positive constant. The positive direction for all vector quantities
is upward. Express all algebraic answers in terms of M, k, vo, and fundamental constants.
a. Does the magnitude of the acceleration of the ball increase, decrease, or remain the same as the ball moves
upward?
increases decreases remains the same
Justify your answer.
b. Determine the terminal speed of the ball as it moves downward.
c. Does it take longer for the ball to rise to its maximum height or to fall from its maximum height back to the
height from which it was thrown?
longer to rise longer to fall
Justify your answer.
d. On the axes below, sketch a graph of velocity versus time for the upward and downward parts of the ball's
flight, where tf is the time at which the ball returns to the height from which it was thrown
