Question

What is the kinetic energy of a 54 kg mass traveling at 15 meters per second?
kg * m/8
405

kg * m^2/8^2
6075

kg * m/8
420

kg * m^2/8^2
12,150

Answer 1

Given that an object with a mass of 54kg travels at 15m/s^2, determine the kinetic energy of the object.

KE =  0.5 x mv^2

M (mass) = 54kg

V (velocity) = 15m/s^2

Then, we plug the values in.

KE =  0.5 x 54(15^2)

Now, we solve.

KE = 0.5 x 54(225)

KE = 0.5 x 12150

KE = 6075

Now, that we have solved the formula, we can see that the kinetic energy of the object is 6,075J.

Thus, the kinetic energy of the object is 6,075J.
