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. 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?
