Question

A particle moving in a straight line travels the first t sec with velocity v1 and the next t sec with velocity v2.The average velocity of the particle over the time interval 2t sec is​

Answer 1

Answer:

(v1+v2)/2

Explanation:

for first t sec distance travelled = v1×t

Fir next t sec distance travelled = v2×t

total distance travel = v1t+v2t

average velocity = total distance covered / total time taken

= (v1t+v2t)/2t

= (v1+v2)/2
