A police officer arrives on the scene of a one-vechicle auto accident. The only information that she has is the 200 foot skid marks on the road before the car hit the barricade. Weather doesn't seem to be a factor. Can she figure out how fast the car was going before the driver hit the brakes? If so, what was it if the standard braking deceleration used by police departments is -16-2?

Question
A police officer arrives on the scene of a one-vechicle auto accident. The only information that she has is the 200 foot skid marks on the road before the car hit the barricade. Weather doesn't seem to be a factor. Can she figure out how fast the car was going before the driver hit the brakes? If so, what was it if the standard braking deceleration used by police departments is -16-2? What is the volume of the figure produced by a rectangular region inthe first quadrant bounded by x = 0, x = 4, y = 0, and y = 6? What is the shape and volume of the solid formed by rotating the curve y = ex around the x-axis between x = -1 and x = 1?
