Question

The motion of particle along the x axsis is given by x=9+5t square find the average velocity in the time intervals t=3 s

Answer 1

Answer:

         V = 30m/s

Explanation:

Velocity = dx / dt

V = dx / dt

V = d (9 + 5t²) / dt

V = d(9) / dt + d(5t²) / dt

V = 0 + 10t

V = 10t

t = 3

V = 10 × 3

V = 30m/s
