In a design test of penetration resistance, a 13-g bullet is fired through a 460-mm stack of fibrous plates with an entering velocity of 600 m/s. if the bullet emerges with a velocity of 360 m/s, calculate the average resistance r to penetration. what is the loss δq (enter as positive number) of energy and where does it go?

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=?
