Question

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

Answer 1

Velocity would be 12 m/s

Answer 2

The velocity of cheetah is 12 m/s.

Step-by-step explanation:

Given that,

Mass = 50 kg

Energy = 3600 J

We need to calculate the kinetic energy

Using formula of kinetic energy

`K.E=(1)/(2)mv^2`

`v^2=(2* K.E)/(m)`

Where, K.E = kinetic energy

M = mass

Put the value into the formula

`v=\sqrt{(2*3600)/(50)}`

`v=12\ m/s`

Hence, The velocity of cheetah is 12 m/s.
