Question

A ball is thrown straight up. At the top of its path its acceleration is

a. 0 m/s^2
b. about 5 m/s^2
c. about 10 m/s^2
d. about 20 m/s^2
e. about 50 m/s^2

Answer 1

At the top of its path, a ball thrown straight up still experiences an acceleration of about 9.8 m/s^2 downward due to gravity.

Step-by-step explanation:

When a ball is thrown straight up, at the top of its path its acceleration is about 10 m/s2. Despite the velocity being zero at the highest point, the acceleration due to gravity is still acting on the ball. Therefore, the correct answer is (c) about 10 m/s2, or more precisely, 9.8 m/s2, downward, due to the acceleration of gravity.
