Question

The velocity of a body moving along the x-axis is given by the equation v=3t^(2) where t is in sec&v in m/s .The body is at x=+36 m at t=0 .The average velocity (in m/s) of the body in the time interval between t=0 and t=3 sec is​

Answer 1

Answer:

average velocity = 13.5m/s

Explanation:

we can consider the body to be at rest at x=+36 m as no information regarding velocity is given before it so.

Velocity = 3×3² = 27m/s

at t=0 ,v=0

Therefore average velocity =

(0+27)/2 = 13.5m/s
