Question

A car initially going 72 ft/sec brakes at a constant rate (constant negative acceleration), coming to a stop in 8 seconds.
Graph the velocity for t = 0 to t = 8. How far does the car travel before stopping?
distance = 288ft (include units)
How far does the car travel before stopping if its initial velocity is doubled, but it brakes at the same constant rate?
distance =
(include units)
