Question

A lazy bowler pulls his arm back and then lets only gravity pull the ball back around in an arc while he just holds on to the ball. At the moment when the ball has reached its highest forward point in the arc, he lets go. The ball will o a. fall from rest to the ground. o b. eave his hand with a velocity that has components both in the upward and the horizontal directions. o c. leave his hand with a velocity that only has a horizontal component. • d. leave his hand with a velocity that only has a vertical component.

Answer 1

The ball will a. fall from rest to the ground.

Step-by-step explanation:

As the ball is released at its highest forward point, its potential energy is maximized. This would mean all the kinetic energy has been transferred to potential energy (according to the law of energy conservation). The ball leaving hand without any kinetic energy would have no initial speed. Therefore, it would just fall from rest to the ground due to gravity.
