Part (a). P = 0. Since the force F needed to keep the crate from moving is larger than the maximum friction force Fmax that is available, we know that the crate does move. Solve for the acceleration of the block. We will assume that the acceleration is positive if it moves up the slope. mg N Answer:a = i m/s2
