Question

a block of mass 30 kg is pulled up a slope with a constant speed by applying a force of 200 Newton parallel to the slope a and b are the initial and final position of a block
calculate
(1) the work done by the force in moving the block from a to b
(2) the potential energy gained by the block

Answer 1

$p.e. = mgh \\ =200 \times 30 \\ = 6000j$
