4. An object moving with a speed of 35m/s and has a kinetic energy of 1500 J,what is the mass of the object.

Question

Answer 1

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

where:-

is the kinetic energy,-

is the mass,-

is the velocity.Given:-

-

We need to solve for

:

First, calculate \( (35)^2 \):

Now, substitute this back into the equation:

Multiply both sides by 2 to isolate

:

Finally, divide both sides by 1225 to solve for

:

So, the mass of the object is approximately
