A force of 20 N acting at an angle of 60° to the horizontal is used to pull a box through a distance of 3 m across a floor. How much work is done? 5.3. An engine raises 100 kg of water through a height of 80 m in 25 s. What is the power of the engine? 5.4. A body of mass 20 kg is at rest. A 40 N force acts on it for 5 seconds. What is the kinetic energy of the body at the end of this time? 5.6. A 0.14 kg ball is thrown vertically upward with an initial velocity of 35 m s⁻¹. Find the maximum height reached by the ball. 5.10. A box of mass 10 kg is pushed up along a ramp 15 m long with a force of 80 N. If the box rises up a height of 5 m, what is the efficiency of the system? 5.11. A force of 600 N acts on a box to push it 5 m in 15 s. Calculate the power.
