A particle starting from rest undergoes a rectilinear motion with acceleration a. The variation of a with time t
is shown below. The maximum velocity attained by the particle during its motion is
(1) 120 m/s
(3) 22 m/s
(2) 60 m/s
(4) 80 m/s
with explanation

Answer:
Answer is option A. 120m/s
Explanation:
Becoz in its entire motion the maximum acceleration is at 12s of magnitude 10m/s^2
Hence by the formula-
v=u+at (u=0)
v=0+10×12=120m/s
