PLEASE HELP

1. Katie is bowling. She starts with the ball in her right hand and her arm as far back as it will go. She swings the ball forward, applying a force of 78 Newtons the whole time. When her hand has traveled through a path of 0.9 meters, she releases the ball, and it rolls down the lane.

How much work is involved in this example?
A.0 N⋅m
B.70.2 N⋅m
C.94 N⋅m
D.Andy pushes a desk across the floor.

To calculate the work involved in this example, we need to use the formula:

Work = Force x Distance

Given that the force applied is 78 Newtons and the distance traveled is 0.9 meters, we can calculate the work involved as:

Work = 78 N x 0.9 m
Work = 70.2 N⋅m

So, the correct answer is B. 70.2 N⋅m.

As for D. Andy pushes a desk across the floor, we don't have enough information to calculate the work involved in that scenario. We would need to know the force applied and the distance the desk is moved.
