Answer:

816.33 kg

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
