1) A force of 24N is used to push a box 10m across the floor. Calculate the work done on the box:
2) A fisherman pulls in a huge fish with a force of 5N. They do 250J of work. How far have they pulled the fish in?
3) A vehicle accelerates from 4m/s to 12m/s. How much work was done if the mass of the vehicle was 1000kg?
4) A strong woman deadlifts a 160kg from the floor to a height of 1.8m. Calculate the work done on the weights:
3) 64000J (64 kJ)
4) 2822.4 J
