Question

A body started from rest at point ‘A’ and attained a final velocity of 80ms-1 at point ‘B’ in a time interval of 12 sec as shown in the figure.​

Answer 1

Step-by-step explanation:

Correct option is

A

Zero

Suppose the acceleration is a then using the second equation of motion, s=ut+

2

1

at

2

and putting t=2sec and u=10m/s

we get 20=10×2+a×2

or a=0 that is uniform motion.
