Question #294928

Determine the mass of a moving object with a velocity of 35 m/s and a kinetic energy of 58 J.

Expert's answer

Given:

$v=35\:\rm m/s$

$E_k=58\:\rm J$

The kinetic energy is given by

E_k=\frac{mv^2}{2}

The mass of object

m=\frac{2E_k}{v^2}=\frac{2*58\:\rm J}{(35\:\rm m/s)^2}=0.095\:\rm kg
