Question

As a physics instructor hurries to the bus stop, her bus passes her, stops ahead, and begins loading passengers. She runs at 6.0 m/s to catch the bus, but the door closes when she's still 5.5 m behind the door, and the bus leaves the stop at a constant acceleration of 2.0 m/s2. She has missed her bus, but as a physics exercise she keeps running at 6.0 m/s until she draws even with the bus door.

Calculate Δt from the instant the bus leaves the stop to the instant the instructor draws even with the door.

At the instant she draws even, how fast is she moving?

At the instant she draws even, how fast is the bus moving?
