Which of the following has a higher kinetic energy?

A 1000 kg car rolling at a speed of 5 m/s across the floor or a 1500 kg hippo swimming at a speed of 2 m/s.

A. their kinetic energies are equal
B. the hippo
C. not enough information to determine
D. the car

C. not enough information to determine

The kinetic energy of an object is calculated using the formula KE = 0.5 * mass * velocity^2. In order to determine which has a higher kinetic energy, we would need to calculate the kinetic energies of both the car and the hippo using this formula. Without knowing the specific values for the mass and velocity of each object, we cannot determine which has a higher kinetic energy.
