What is the mass of an object travelling at 15 m/s with a kinetic energy of 100 J?

Kinetic Energy (E k ) = 1/2(mv 2 ).This can be rearranged such that, m = (2E k )/v 2 we know from the question that E k = 100 J and we know that v = 15 m/sso plugging in the numbers, we get m = (2 x 100)/(15...

What is the momentum of a 84 kg man running at 5 m/s?

Use the equation p= m x v , where p=momentum m=mass (kg) and v=velocity (m/s)p= 84x5 = 420 kg m/s
