A car of mass 1000 kg is moving with a velocity of 10 \mathrm{m.s^{-1}}. 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 25s will be:
a) 25 \mathrm{m.s^{-1}}
b) 40 \mathrm{m.s^{-1}}
c) 10 \mathrm{m.s^{-1}}
d) 250 \mathrm{m.s^{-1}}
Solution
Transcript
The correct answers is c) 10 \mathrm{m.s^{-1}}
"hey guys welcome to lido q a video i am vinit your leader tutor bringing you this question on your screen a car of mass 1000 kg is moving with a velocity of 10 meter per second 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 second will be so let us draw the velocity time graph right so let us say time is along x axis and velocity is along y axis increasing as you go now the question says if the velocity time graph for this car is a horizontal line parallel to the time axis so let's say ah the velocity is 10 so let's say this is 2 4 6 8 and 10 and this is time so the initial values velocity is 10 and the velocity a graph time graph is a horizontal line parallel to the time axis now we see the velocity is constant throughout hence the velocity will be 25 meter per second at any given time right irrespective of the mass and and the time taken right therefore velocity after 25 seconds is equal to 10 meter per second right so the velocity will still be 10 meter per second a constant velocity throughout right guys wasn't that easy okay if you still have a doubt please leave a comment below and do like the video and subscribe to our channel i'll see you in our next video until then bye kids keep learning"
