Michael has set the gauge pressure of the tires on his car to 36.0 psi (lb/in2). He draws chalk lines around the edges of the tires where they touch the driveway surface to measure the area of contact between the tires and the ground. Each front tire has a contact area of 24.0 in 2 and each rear tire has a contact area of 20.0 in2.
(a) What is the weight (in lb) of the car?
(b) The center-to-center distance between front and rear tires is 7.00 ft. taking the straight line between the centers of the tires on the left side (driver's side) to be the y -axis with the origin at the center of the front left tire (positive direction pointing forward), what is the y - coordinate of the car's cm?
