Question

a An object is moving mith a uniform acceleration () Starting with an initial velocity (u). It acquires the final nelocity (v) in the time internal (it). Represents the distance travelled by the object in the time interval (3)​

Answer 1

Answer:

Correct option is

B

(v−

Substitute, u=v−at in the above expression:

We get average velocity =v−at+
