A body starts from rest at time `t = 0` , the acceleration time graph is shown in the figure . The maximum velocity attained by the body will be

Text Solution

Verified by Experts

The correct Answer is:
55
As change in velocity = area under acceleration - time graph
`:. Delta v = (1)/(2)`(10)(11)
or `Delta v = v - u = 55m/s`
But u = 0 (as body starts from rest)
`:. v = v_("max") = 55 m//s `
Thus , the maximum velocity attained by body will be 55 m/s
