Question

Car of mass 1000 kg is moving with a velocity of 10 m/s. If the velocity-time graph for this car is a horizontal line parallel to the time axis, then the velocity of the car at the end of 25 s will be

Answer 1

Answer:

10 m/s

Explanation:

Given that,

Mass of car = 1000 Kg

Initial velocity, u = 10 m/s

Also, its given that,

Velocity-time graph for this car is a horizontal line parallel to the time axis.

To find it's velocity at the end of 25 s.

Since, the graph is parallel to time axis,

It means that,

The time is increasing but the velocity is constant.

Therefore, at the end of 25 s also, velocity will be same as initial one.

Hence, required velocity of the car is 10 m/s.

Answer 2

The correct answer is 10 m/s
