Question

The velocity-time graph of a body is shown below:

(a) State the kind of motion represented by OA and AB.

(b) Find the velocity of the body after 10 s and after 40 s.

(c) What is the negative acceleration of the body?​

Answer 1

Explanation:

A) OA- accelerated

OB - constant

B) Use (V-U)/T In both cases

1 I'll show you 0-20/10

= -20/10 = -2m/s²

C) According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration.
