Question

A 50 kg cheetah has 3,600 J of kinetic energy. What is its velocity?

Answer 1

12 m/s on the assignment

Answer 2

To determine the velocity, let us use the equation:

v = √$\frac{2K}{m}$

The kinetic energy (K) is equivalent to 3,600 J, and mass (m) is equivalent to 50kg.  Let us now solve for velocity.

v = √$\frac{2K}{m}$
v = √$\frac{2 (3,600 J)}{50 kg}$
v = √$\frac{7,200}{50}$
v = √144
v = 12

The velocity of the tiger is 12 meter/second.
