Two motorcycles are traveling due east with different velocities. However, four seconds later, they have the same velocity. During this four-second interval, cycle A has an average acceleration of 2.0 m/s2 due east, while cycle B has an average acceleration of 4.0 m/s2 due east. By how much did the speeds differ at the beginning of the four-second interval, and which motorcycle was moving faster? |
