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.

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.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
