Solution
50 m
Explanation:
Distance covered = Area under velocity – time graph
=1/2 × base × height
a = 1/2 × 5 × 20 = 50 m

Which of the following graphs represents a motion with negative acceleration?
Draw the distance-time graphs of the bodies P and Q starting from rest, moving with uniform speeds with P moving faster than Q.

(i) In speed time graph uniform motion is given by a straight line parallel to x axis so figure (a) denotes the uniform motion.
(ii) In speed time graph motion with increasing speed is shown by straight line with positive slope so figure (c) denotes the motion with speed increasing.
