Answer to Question #17059 in Molecular Physics | Thermodynamics for KRISTIN

Question

A juggler throws a ball with an initial horizontal velocity of +1.1 m/s and an initial vertical velocity of +5.7 m/s. What is its
acceleration at the top of its flight path? Make sure to consider the sign when responding. Consider the upward direction as positive.

Answer 1

The acceleration remains constant during all time of flight of the ball
and equals to -g = -9.8 m/s2 (downward)& if we assume the upward
direction as positive.
