Answer:
Displacement is the distance and direction an object is moved. Force and work are directly proportional to each other, while force and displacement are indirectly propotional. The equation showing the relationship is W= Fd. OR Work is a scalar. The rate at which work is done or at which energy is transferred. Work is equal to the force parallel to the displacement.

Answer:H=34.05m
Explanation: H=u²/2g+ 28m height of the cliff
u=11ms⁻¹
g=10ms⁻²
H=11²/2*10
H=121/20
H=6.05+28
H=34.05m
