a rock has a kinetic energy of 110 j and is traveling at a velocity of 3 m/s. What is the mass of the object?

Answers & Comments

$\tt{\huge{\blue{Explanation:}}}$

The mass of a moving object is given by

$\boxed{m = \frac{2KE}{v^{2}}}$

where:

m = mass

KE = kinetic energy

v = speed

$\tt{\huge{\red{Solution:}}}$

Solving for the mass

$m = \dfrac{2KE}{v^{2}}$

$m = \dfrac{2(\text{110 J})}{(\text{3 m/s})^{2}}$

$\boxed{m = \text{24.44 kg}}$

Therefore, the mass of the rock is 24.44 kg.
