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]
