Physics 1 Review Question 1

An athlete running 2.6 m/s increases his velocity to 3.7 m/s in 2.7 s. What is the acceleration of the runner? Round your answer to the nearest hundredth. 

Answer 1

Acceleration, a, is the increase in velocity per unit time:

a = (3.7 m/s - 2.6 m/s) / 2.7 s = 0.41 m/s².
