Question

Two motorcycles are traveling due east with different velocities. However, 5.25 seconds later, they have the same velocity. During this 5.25-second interval, motorcycle A has an average acceleration of 4.43 m/s2 due east, while motorcycle B has an average acceleration of 17.5 m/s2 due east. (a) By how much did the speeds differ at the beginning of the 5.25-second interval, and (b) which motorcycle was moving faster?
