the change in velocity takes place in 10 sec interval. What is the magnitude, the algebraic sign and the direction of the average acceleration in each interval?

At the beginning of the interval a body is moving to the right along the x-axis at 5 ft/sec, and at the end of the interval, it is moving towards the right at 20 ft/sec.

1 answer

a = (V-Vo)/t = Acceleration in Ft./s^2
V = 20 Ft/s.
Vo = 5 Ft/s.
