Two motorcycles are traveling due east with different velocities. However, 2.04 seconds later, they have the same velocity. During this 2.04-second interval, motorcycle A has an average acceleration of 4.98 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 2.04-second interval, and (b) which motorcycle was moving faster?

An elevator is moving upward with a velocity of 15 m/s. Three seconds later, the elevator is still moving upward, but its velocity has been reduced to 6.0 m/s. What is the average acceleration of the elevator during the 3.0 s interval? After 3.0 s, If it maintains the same acceleration, what is the displacement of the elevator after 5 second time interval ? What will be the velocity after the 5 second ? Hint: Keep in mind that the...
