Which of the following objects has the greatest kinetic energy?A. a car traveling at 35 miles per hour B. a horse sprinting at 35 miles per hour C. a baseball flying at 35 miles per hour D. an insect flying at 35 miles per hour E. All four objects have the same kinetic energy.

Respuesta :

Answer: The car if it weighs more than the horse

Explanation: Kinetic energy is proportional to the object's mass and velocity, so higher the mass and velocity the more kinetic energy it will have. In this case as all the objects have the same velocity we have to consider their masses and thus, the car assumingly has the greatest kinetic energy

Answer:

A car traveling at 35 miles per hour

Explanation:

Kinetic energy is the energy possessed by an object having motion. The kinetic energy depends on the mass and speed of the object:

K.E. = 0.5 mv²

In the given options, all the things have same speed. So, the kinetic energy can be compared on the basis of the mass. The car is the heaviest among the given four options. Thus, the car traveling at the 35 miles per hour has the maximum kinetic energy.
