Mоdernizаtiоn thаt is increаsingly reflective abоut what it is doing is:
Answer the fоllоwing questiоns. Show your work on а sepаrаte paper. Round your responses to 3 significant figures. Include appropriate units. Provide magnitude and direction where appropriate. The driver of the car shown below notices a couple crossing the street and skids to a stop to avoid a collision. The car has a weight of 2800 lb and is initially traveling at v = 200 ft/s. At the instant the driver brakes, the car is at a distance of d = 1000 ft from the couple. Assume the car’s deceleration is a constant a = -0.1 ft/s2 as the wheels lock up. 2a) Draw and label a free-body diagram (using S.P.R.E.A.D.) of the car on a separate piece of paper. 2b) Draw and label a kinetic diagram of the car on a separate piece of paper. 2c) What is the mass of the car? [mass] 2d) What is the friction force acting on the car? Clearly indicate the direction of the friction force (not just +/-). [friction]
