Question

3) A body starts from rest at t = 0, the acceleration time graph is show. The distance travelled by the body from t = 4s to t = 8s will be
1) Om
2) 16 m
3) 32 m
4) 64 m​

Answer 1

Ans : 64

Explanation : Attached

Answer 2

Given:

Time at which the body was at rest = 0 sec

To find:

The distance traveled by the body from t=4 sec to t=8 sec.

Solution:

First, we need to make a velocity vs time graph with the help of the given acceleration graph.

Now, we need to calculate the area of the velocity vs time graph to calculate the distance traveled by the body. The area will be:

= 4×16 = 64 m

The correct option is 4, i.e. 64m distance traveled by the body.
