Question

an object is moving at a velocity of 23 m/s. it accelerates to a velocity of 85 m/s over a time of 8.5 s. what acceleration did it experience?

Answer 1

|Acceleration| = (change in speed) / (time for the change)

|Acceleration| = (85 m/s - 23 m/s) / (8.5 sec) =

(62 m/s) / (8.5 sec) =

(62 / 8.5) (m / sec²) = 7.294 m/s² (rounded)
