Question

two similar buses are moving with same velocity on a road. one of them is empty and the other is loaded with passengers. which of the two will be stopped by the application of less force? explain. ​

Answer 1

Answer:

Loaded

Explanation:

Loaded bus will stop with less force because it has loaded

Answer 2

Answer:

The bus, which is empty, will stop with the application of less force.

Explanation:

• When two similar buses, one which is empty and one which is loaded with passengers, move at the same velocity, the bus which is empty will stop with the application of less force.
• This is because the bus loaded with passengers has more mass compared to the bus that is empty.
• Thus, more force is required to stop the bus loaded with passengers (force is directly proportional to mass).
• It is easier to stop the empty bus because its kinetic energy is less than that of the other bus loaded with passengers.
• As we know, kinetic energy is directly proportional to the mass of a body moving at a uniform speed.
• Thus, higher mass means more kinetic energy and therefore requires the application of great force.
