Question

A cricket ball hits and breaks a glass window and ends up inside the house. Identify which of the following statement is correct about the ball?

• A. The force the ball exerted on the window was larger than the force the window exerted on the ball
• B. The force the ball exerted on the window was smaller than the force the window exerted on the ball
• C. The force the ball exerted on the window was the same as the force the window exerted on the ball
• D. Since the ball broke the window, it didn't lose any momentum
• E. The kinetic energy the ball had before it broke the window equaled the kinetic energy the ball had after it broke the window

Answer 1

The correct option is C The force the ball exerted on the window was the same as the force the window exerted on the ball

According to Newton's third law, if a body exerts a force on another body, another body will exert an equal force on the first body. Therefore the force the ball exerts on the window is the same as the force the window exerts on the ball.
