To determine which ball the bowler should use to increase their acceleration and knock down all the pins, we need to understand the physics involved in the motion of the ball and pins.
The key idea here is that the force exerted by the ball on the pins (also known as the impact force) is directly proportional to the acceleration of the ball. So, if we want to increase the acceleration and subsequently increase the impact force, we need to consider a few factors.
First, let's consider mass. According to Newton's second law of motion, the acceleration of an object is inversely proportional to its mass when the force acting on it is constant. This means that a ball with less mass will experience a greater acceleration for the same amount of force applied.
Secondly, let's consider force. When it comes to throwing the ball, a greater force applied will result in a greater acceleration. By applying more force, the bowler can increase the acceleration of the ball.
Considering these factors, we have two options:
1. The bowler should choose a ball with less mass (option 2) or throw the ball with more force (option 1). Both of these choices will result in an increase in acceleration and therefore increase the impact force on the pins.
So, the correct answer is either option 1 or option 2. The bowler can either choose a ball with less mass or throw the ball with more force to increase their acceleration and knock down all the pins.
