Question

if you throw a baseball straight up, what is its velocity at the highest point? 9.8 m/s² 9.8 m/s 0 m/s² 0 m/s

Explanation:

Step1: Analyze motion at highest point

When a baseball is thrown straight up, at the highest - point of its motion, it momentarily stops before starting to fall back down. Velocity is the rate of change of displacement. At the instant it stops, its speed is 0. Also, the units of velocity are m/s (while m/s² is the unit of acceleration).

Answer:

D. 0 m/s
