A uniformly accelerated car passes three equally spaced, Ask an Expert

Academics

"A uniformly accelerated car passes three equally spaced traffic signs. The signs are separated by a distance d = 25 m. The car passes the first sign at t = 1.3 s, the second sign at t = 3.2 s, and the third sign at t = 5.1 s.

(a) What is the magnitude of the average velocity of the car during the time that it is moving between the first two signs?

(b) What is the magnitude of the average velocity of the car during the time that it is moving between the second and third signs?
