Question

An object has a kinetic energy of 88 J and a mass of 45 kg , how fast is the object moving?

Answer 1

1.98 m/s

Step-by-step explanation:

The velocity of the object can be found by using the formula

where

m is the mass

KE is the kinetic energy

We have

We have the final answer as

1.98 m/s

Answer 2

The answer is 1.98 m/s

Step-by-step explanation:

The velocity of the object can be found by using the formula

`v = \sqrt{ (2KE)/(m) } \\`

where

m is the mass

KE is the kinetic energy

We have

`v = \sqrt{ (2 * 88)/(45) } = \sqrt{ (176)/(45) } \\ = 1.97765292`

We have the final answer as

1.98 m/s

Hope this helps you
