Question

What is the kinetic energy of a 1 kilogram ball is thrown into the air with an initial velocity of 30 m/sec

Answer 1

To find this we should use the equation Ek=1/2mv^2 where Ek is the kinetic energy, m is the mass and v is the velocity. So by this Ek=1/2*1*30^2 which then makes Ek=450 joules
