Question

Solve the following problems: (only for genius)

1) Calculate the kinetic energy of a girl of mass 25kg running at a velocity of 3m/s.

2) A car's velocity increases from 36km/h to 72km/h . The car weighs 1400kg. Calculate the work done by the engine.

3) Calculate the potential energy of a stone of mass 500g raised to a height of 12m above the ground. Assume that acceleration due to gravity g= 10m/s²

Give the correct answer, I will mark u as branliest. ​
