Physics Practice Problems Work By Gravity & Inclined Planes Practice Problems Solution: You need to raise a heavy block by pulling it with...

⚠️Our tutors found the solution shown to be helpful for the problem you're searching for. We don't have the exact solution yet.

Solution: You need to raise a heavy block by pulling it with a massless rope. You can either (a) pull the block straight up height h, or (b) pull it up a long, frictionless plane inclined at a 15 angle until its height has increased by h. Assume you will move the block at constant speed either way.Will you do more work in case a or case b? Or is the work the same in both cases?
