Question

The acceleration-time graph am/s2
of a particle moving in a
straight line is as shown in
figure. The velocity of the
particle at time t = 0 is 2
m/s. The velocity after 2
seconds will be
(a) 6 m/s
(6) 4 m/s
(c) 2 m/s
(d) 8 m/I​

Answer 1

v = u +at

a*t= area undet A vs t graph = 0.5*4*2 = 4

=> v = 2 +4
= 6 m/s

Option A
