Question

After the ball has left the bat, and while it is traveling upward (at point P in the figure (Figure 1) ), what is the direction of acceleration (Figure 2) ? Ignore air resistance.

Answer 1

Answer:

during the motion of the ball the acceleration is due to gravity which is always downwards.

Explanation:

While ball is moving upwards after being hit by the bat then the net force on the ball is given as

$F = - F_g$

so here the negative sign shows that direction of force is opposite to the direction of velocity which is downwards

so we have

$a = - g$

$a = - 9.81 m/s^2$

so during the motion of the ball the acceleration is due to gravity which is always downwards.

Answer 2

From the moment the ball leaves the bat until the moment the ball hits the ground, its acceleration is 9.8 m/s^2 directed downward. That's the acceleration of gravity.
