Question

A ball is thrown straight up. At the top of its path its acceleration has a value (magnitude) of _____.

a. 0 m/s/s0 m/s/s.
b. about 5 m/s/s5 m/s/s.
c. about 10 m/s/s10 m/s/s.
d. about 20 m/s/s20 m/s/s.
e. about 50 m/s/s50 m/s/s

Answer 1

c.

A ball thrown up only experiences the Earth's gravitational acceleraion, and it is uniform near the earth's surface. The magnitude of gravitational acceleration is 9.81 m/s², so the closest value is 10.
