Homework Statement
A block is given initial velocity of 5m/s up a frictionless 20 degrees incline. How far up the incline does the block slide before coming to rest?
The answer is 3.73m.
I set the coordinates to be perpendicular to the plane instead of parallel to the incline. I calculated the vertical and horizontal displacement and then use Pythagorean Theory to evaluate how far the car goes. But I did not get the expected answer, which is 3.73. Can anybody tell me what's wrong with my solusions?
