Question

a body starts from rest at time t is equal to zero the acceleration time graph is shown in the figure the maximum velocity attained by the body will be is equal to 10 M per second and 30 equal to 11 seconds

Answer 1

The change in velocity is given by the area under the a-t graph and here it is1/2×11×10=55

As initial velocity is 0 therefore max velocity is 55m/s

Answer 2

Answer: The correct answer is 55 m/s.

Explanation:

In the given problem, the body starts from the rest. Then, the initial velocity of the body is zero.

Calculate the area under the curve to get the value of maximum velocity.

Area of the triangle=v= $\frac{1}{2} BH$

Here, B is the base and H is the height.

Put B= 11 s and H= 10 meter per second square in the above expression.

v= $\frac{1}{2} (11)(10)$

v= 55 m/s[/tex]

Therefore, the value of maximum velocity attained by the body is 55 m/s.
