Question

The v-t graph of a moving object is given in figure.
The maximum acceleration is
60F
Velocity (cm/sec)
40H
20)
10 20 30 40 50 60 70 80
Time (sec.)
(1) 1cm/sec
(2) 2 cm/sec
(3) 3 cm/sec
(4) 6 cm/sec​

Answer 1

This is the second time I'm answering this question, lmao. But I will answer it again.

First acceleration = 20-0/20 = 1 m/s.

Second acceleration = 0 because object is moving at constant velocity.

Third acceleration = 80-20/10 = 6 m/s.

Fourth acceleration = 80-0/40 = 2m/s.

Hence max. acceleration is 6m/s.
