Question

A cannon that sits 1.3m off the ground, shoots a 14kg
into the air vertically at 9.6 m/s. What is the acceleration of the ball at its
highest point?

Answer 1

Answer:

0 m/s2

Explanation:

Since the peak of the ball is when there is no acceleration in the y direction (it is just floating in air for a point in time), and the ball is being shot vertically, the acceleration at its highest point is 0.
