A carton loaded with saline infusion of total mass of 100kg falls down from a lorry of 2.0m high. Calculate the work done by gravity on the loaded carton
The work done by gravity on the loaded carton is equal to the gravitational potential energy of the carton. The gravitational potential energy of the carton is equal to the mass of the carton multiplied by the acceleration due to gravity multiplied by the height of the lorry. Therefore, the work done by gravity on the loaded carton is equal to 100 kg x 9.8 m/s2 x 2.0 m = 1960 J.
