Question

3. During a race, a sprinter increases from 5.0 m/s to 7.5 m/s over a period of 1.25s. What is the sprinter’s average acceleration during this period?
Also please try and explain
Please and Thank you

Answer 1

(7.5)-(5)
----------- = 2 m/s^2
(1.25-0)

Average acceleration is calculated using the equation V(f)-V(i) / t(f)-t(i). (Final velocity minus initial velocity divided by final time minus initial time)
