Question

Calculate the kinetic energy of a 750 kg compact car moving at 50 m/s:

a. 937500 J
b. 625000 J
c. 468750 J
d. 375000 J

Answer 1

The kinetic energy of the car is 937500 J.

Step-by-step explanation:

The kinetic energy of an object can be calculated using the formula KE = 1/2 * m * v^2, where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object. In this case, the mass of the car is given as 750 kg and the velocity is given as 50 m/s. Plugging these values into the formula, we get:

KE = 1/2 * 750 kg * (50 m/s)^2 = 937500 J.

Therefore, the correct answer is (a) 937500 J.
