In order for you to jump a distance of 4 feet horizontally, you must exert a force of 200 N.
When you are standing on the ground, you have
no trouble doing this. If you are standing in a
canoe, however, and you need to jump 4 feet to
reach the pier, you will surely fall in the water
Why is it that you cannot jump 4 feet out of a
canoe when you can easily do this when on land?
