a block, m= 3 kg, slides on a frictionless horizontal surface.It then goes up a 15 degree incline having a coeffecient offriction uk=0.30 a distance L before stopping. The initial velocityof the block on the horizontal sureface is 2 m/s.
a) find the acceleration of the block on the plane. Why is itnegative?
b) find the distance L in meters.
