The side of the base of a square prism is increasing at a rate of 555 meters per second and the height of the prism is decreasing at a rate of 222 meters per second. at a certain instant, the base's side is 666 meters and the height is 777 meters. what is the rate of change of the volume of the prism at that instant (in cubic meters per second)?

You are driving to the grocery store at 20 m/s. you are 110m from an intersection when the traffic light turns red. assume that your reaction time is 0.50s and that your car brakes with constant acceleration. how far are you from the intersection when you begin to apply the brakes? what acceleration will bring you to rest right at the intersection? how long does it take you to stop after the light changes? the known values: vi=20m/s xi=110m t=.50s vf=0m/s xf=0m a=?
