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.
