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 $25seconds$ will be what?

Answer 1

Step 1: Given

Mass of the car, $m=1000Kg$

Velocity, $v=10m/s$

Time, $t=25seconds$

Step 2: Determine the velocity at the end of $25seconds$

1. The velocity-time graph for this car is a horizontal line parallel to the time axis.
2. The velocity is measured along the y-axis of the graph and the time is measured along the x-axis.
3. That is, the velocity is not changing with respect to time
4. Hence, the velocity at the end of $25seconds$ is also $10m/s$.

Therefore, the velocity at the end of $25seconds$ will be $10m/s$.
