Question

URGENT!!
WITH EXPLANATION!!
A body starts from rest at time t = 0, the acceleration time graph is shown in figure. The maximum
velocity attained by the body will be:
(Delhi/ NTSE Stage-1/2014)
(A)1110 m/s
(B) 55 m/s
(C) 650 m/s
(D) 550 m/s​

Answer 1

Answer:

Option(B)

Step-by-step explanation:

The body is starting from rest, t = 0.

The area under acceleration-time graph gives the change in velocity.

Thus, maximum velocity will be,

=> (1/2) * 10 * 11

=> 5 * 11

=> 55 m/s

It is given that initial velocity is 0, the maximum velocity attained = 55 m/s.

Therefore, maximum velocity is 55 m/s.
