A block is given an initial velocity of 3.00 m/s up a frictionless 22.0° incline. How far up the incline does the block slide before coming (momentarily) to rest? So basically, how far does it go up before the block starts falling. http://img11.paintedover.com/uploads/11/p522.gif At first glance, this seemed really simple to me. Here's what I tried: The initial velocity in the Y direction would be 3sin(22) = 1.12 m/s Then I used the formula Vf2 = Vi2 + 2*(-9.8)*(delta Y) -->0 = 1.26 - 19.6(delta Y) so delta Y = .064 m. But that is straight up, and I need it along the incline. So, I did sin(22) = (.064)/x and x gives me .17 as the distance up the incline. However, neither .064m or .17m is correct. Can anyone tell me what I'm doing wrong? Am I totally off, or just missing a decimal or something?
