Aball is tossed upward. neglecting air drag, the acceleration along its path is
a) 0 g.
b) g downward.
c) g upward.
d) g upward, then g downward.
e) none of the above

B) g downward

Explanation:

There is only one force acting on the ball during its entire motion: the force of gravity, which pulls the ball downwards. The magnitude of the force of gravity is

where m is the mass of the ball and g is the acceleration due to gravity. Using Newton's second law, F = ma, we can find the acceleration of the ball as:

so, the acceleration of the ball is g, and it is downward (as the force of gravity).
