Question

Select the correct answers from each drop-down menu. A car, a bicycle, a bus, and a motorcycle are moving parallel to each other on a road. Each vehicle is traveling at the same speed. The will have the highest kinetic energy, while the will have the lowest kinetic energy.

Answer 1

Answer: The correct answers are car and the bus.

Explanation:

The kinetic energy is the energy due to the motion of the object.

The expression for the kinetic energy is as follows:

KE=\frac{1}{2}mv^{2}KE=

2

1

mv

2

Here, m is the mass of the object and v is the speed.

The kinetic energy depends on mass of the object and the speed of the object.

In the given problem, a car, a bicycle, a bus, and a motorcycle are moving parallel to each other on a road. Each vehicle is traveling at the same speed. The speeds of the vehicles are same. More the mass of the vehicle, more the speed of the vehicle.

A bus is more heavier than a car and a bicycle. The mass of the bicycle is lesser in comparison to a car and a bus.

Therefore, the bus will have the highest kinetic energy, while the bicycle will have the lowest kinetic energy.
