Need help to solve

Consider a block of mass 14.5 kg being pushed a ϕ=25∘ incline by a horizontal pushing force of magnitude P=154 N. The surface of the incline is rough, so that there is a friction force acting on the block as it slides. Initially the block is moving with a speed of 1.2 m/s, and after the block has been pushed a distance of 6.25 m along the surface of the incline it moves with a speed of 3.3 m/s.


a) After the block has moved the 6.25 m distance along the surface of the incline, how much higher is it than its initial position?

b)Determine the magnitude of the friction force acting on the block.
