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

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.

Answer 2

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

Step-by-step 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.
