A6.25 kg block is sent up a ramp inclined at an angle =31.5° from the horizontal. it is given an initial velocity =15.0 m/s up the ramp. between the block and the ramp, the coefficient of kinetic friction is =0.368 and the coefficient of static friction is =0.663. how far up the ramp in the direction along the ramp does the block go before it comes to a stop?
