As part of a training schedule a weightlifter pushes a heavy metal block
along the floor. The lifter applies a force of 850 N downwards on the block
at an angle of 65 to the vertical (25 to the horizontal). The weightlifter
pushes the block forwards 4 m in 1.6 s. Calculate the power output of the
weightlifter when moving the block 4 m forwards. [10 marks]
