Answer 2

Here is ur answer,

(b) From point A to point B, we see that velocity of the body is remaining constant at40ms−140ms−1. So the body will have zero acceleration. 40ms−140ms−1. So the body will have zero acceleration.

So, we could simply say that AB represents uniform motion.

(c) Now from point B to point C, we see that the velocity is changing uniformly with increasing time. But we can also see that the velocity is actually decreasing with the passage of time.

So, the motion represented by BC would be uniform retarded motion.

(d) Acceleration of the body from point O to point A,

a=ΔvΔta=ΔvΔt

⇒aOA=vA−vOtA−tO⇒aOA=vA−vOtA−tO

⇒aOA=40−010−0⇒aOA=40−010−0

∴aOA=4ms−2∴aOA=4ms−2

The acceleration is found to be 4ms−2.
