Part 1) A small block travels up a frictionless incline that is at an angle of 30.0°above the horizontal. The block has speed 4.26 m/s at the bottom of the incline. Assume g = 9.80 m/s2. How far up the incline (measured parallel to the surface of the incline) does the block travel before it starts to slide back down? Part 2) Complete the following exercises. (Assume g = 9.80 m/s2.) (a) A small block is released from rest at...
