.1. A horizontal force of 60.0 N is applied to a 3.00 kg block. The block is initially at rest and slides a distance of 0.500 m up a ramp once the horizontal force is applied. The ramp is inclined at an angle of 30.0◦ and the coefficient of kinetic friction between the ramp and the block is 0.600. (a) Use Newton’s second law and kinematics to determine how long it took for the block to slide 0.500 m up...
