A game show contestant won a prize by pushing a bowling ball 20 m using her nose. The amount of work done was 1470 J. How much force did the contestant exert on the ball?

W e Fd = 1470J,

20F = 1470,
F = 73.5N.

To calculate the force exerted by the contestant on the ball, we can use the formula:

Force (F) = Work (W) / Distance (d)

Given that the work done (W) is 1470 J and the distance (d) is 20 m, we can substitute these values into the formula:

F = 1470 J / 20 m

F = 73.5 N

So, the contestant exerted a force of 73.5 Newtons on the ball.
