Question

A car travelling

at 35 m/s has a
kinetic energy
of 500,000 J.
what is the
mass?

I NEED HELP FIGURING THIS OUT

Answer 1

816.33 kg

Step-by-step explanation:

To solve this problem we'll need to keep in mind the formula for the kinetic energy of an object:

• E = 0.5 * m * v²

Where E is the kinetic energy, m is the object's mass and v its velocity.

We input the data given by the problem:

• 500000 J = 0.5 * m * (35 m/s)²

And solve for m:

• m = 816.33 kg
