A small block travels up a frictionless incline that is at, Ask an Expert

Academics

A small block travels up a frictionless incline that is at an angle of 30.0 degree above the horizontal. The block has speed 4.69 m/s at the bottom of the incline. Assume g = 9.80 m/s^2. How far up the incline (measured parallel to the surface of the incline) does the block travel before it starts to slide back down?
