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

Question

Answer 1

To find the speed of the object, we can use the formula for kinetic energy:

where

is the kinetic energy,

is the mass, and

is the velocity. We need to solve for

.Given:-

-

Plug these values into the formula:

First, multiply both sides by 2 to get rid of the fraction:

Next, divide both sides by 45 to solve for

:

Calculate

:

Finally, take the square root of both sides to find

:

So, the object is moving at approximately 1.98 meters per second.
