Velocity-Time Graphs

A car of mass...

Question

A car of mass 1000 kg is moving with a velocity of $v = 10 m s^{- 1}$ . 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 s will be :

(a) $25 m s^{- 1}$

(b) $40 m s^{- 1}$

(c) $10 m s^{- 1}$

(d) $250 m s^{- 1}$

Open in App

Solution

Given Data:

Mass of the car,
$m = 1000 k g$
Velocity of the car, $v = 10 m s^{- 1}$
Since, the velocity-time graph for this car is a horizontal line parallel to the time axis, it means velocity will remain constant with respect to time.

Hence, The velocity of the car is 10m/s after 25sec
