Question

A car accelerates from rest with a uniform acceleration of 1.7m/s for 10 seconds, its acceleration then reduces by 0.3m/s for 20 seconds of the motion, it then maintains the speed attained for another 20 seconds after which it decelerates to rest within 10 seconds. Draw the velocity-time graph of the motion and hence calculate the magnitude of the velocity after 10 seconds and 30 seconds.

Answer 1

I don't know how todraw it on this forum. Plot velocity from the given information.
