Q8). A box of mass 72 kg is to be accelerated upwards along a plane inclined at 8 degrees to the horizontal by a force Fp , which is parallel

to the plane and has a magnitude of 360 N . The coefficient of friction between the box and the plane is 0.25. Calculate the acceleration of the block, and hence the time taken for it to slide 5.2 m upwards along the plane, starting from rest.Note: You must draw a diagram of the situation to explain your answer.
