Question

1. Alex pulls on the handle of a claw hammer with a force of 15 N. If the hammer has a mechanical advantage of 5.2, how much force is exerted on a nail in the claw?

2. While rowing in a race, John pulls the handle of an oar 0.08 m on each stroke. If the oar has a mechanical advantage of 1.5, how far does the lade of the oar move through the water on each stroke?

I don't understand how to set them up and do them... Here is the formula I have. Mechanical advantage= output force/ input force=input distance/output distance
