Question

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:

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

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.

Answer 2

Answer: the bus will have the highest kinetic energy and the bicycle will have the lowest kinetic energy

Explanation:

Using the formula

Ke = (1/2)mv^2

We see mad is directly proportional to kinetic energy

The bus will have the highest mass because it is heavier than car and motorcycle and then bicycle will have the least kinetic energy because it's the least mass
