Calculate the kinetic energy of a car of mass 1.0*10^3kg moving at speed of 20ms^-1.

By using the equation: Kinetic Energy = (1/2)mv^2, using m as 1000kg and v as 20ms^-1.We can calculate this value as follows: KE = (1/2)(1000)(20)^2This is equal to 2.0*10^5J (solved using a scientific calculator).
