Question

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

Answer 1

If the velocity time graph for this car is a horizontal line parallel to the time axis,it indicates that carcis moving with uniform velocity ( it covers equal velocity in equal time interval).
∴Velocity of car at the end of 25sec is 10m/s.

Answer 2

Answer: 10 m/s

Given:

Mass = 1000 kg  

Velocity = 10 m/s

To find:

Velocity of car at the end of 25 seconds = ?

Solution:

The above graph is the graph diagram of the velocity time graph which indicates the car is parallel to the time axis. The horizontal line indicates the car. The above graph show that car is moving in uniform velocity which it covers equal velocity in the equal time interval.

Therefore, the car’s velocity that contains 1000 kg at the end of 25 seconds is 10 m/s.
