A dart is thrown straight up. After it leaves the playerâs hand, it steadily loses speed as it gains altitude until it lodges in the ceiling of the game room. Draw the dartâs velocity vector at times t1 and t2, where ?t = t2 – t1 is small. From your drawing find the direction of the change in velocity ?v = v2 – v1, and thus the direction of the acceleration vector.
