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 = √
`(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 = √
`(2K)/(m)`
v = √
`(2 (3,600 J))/(50 kg)`
v = √
`(7,200)/(50)`
v = √144
v = 12

The velocity of the tiger is 12 meter/second.
