6-172.
1. 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 ✎

1. Find a formula for Alice's velocity at time t.

2. Find Alice's displacement between t = 5 and t = 10.

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