6-172.

Bob's cat, Alice, is still doing wind sprints up and down his hallway. This time suppose that Alice's acceleration after *t*seconds is given by the formula. As Alice hits the hallway, her velocity is already 6 feet per second, so *v*(0) = 6. Homework Help ✎Find a formula for Alice's velocity at time

*t*.Find Alice's displacement between

*t*= 5 and*t*= 10.

To find the velocity formula, will need to use the given initial velocity.
