  1. 15 Are you attending lecture today? • Yes • No

  2. A car goes forward along a level road at constant velocity. The total force acting on the tires is • greater than the normal force times the coefficient of static friction. • equal to the normal force times the coefficient of static friction. • the normal force times the coefficient of kinetic friction. • zero.

  3. 15 A dancer stands on her toes. What is the pressure exerted by the floor over the area of contact if the dancer is stationary? • 1.88 x 105 Pa • 2.65 x 105 Pa

  4. :20 Two small cylindrical plastic containers with flat bottoms are placed on a turntable that has a smooth flat surface. Canister A is empty; canister B contains lead shot. Each canister is the same distance rfrom the center. The coefficient of static friction between the canisters and the turntable is . When the speed of the turntable is gradually increased, • only the lighter container slides outward off the turntable; the heavier one stays on. • only the heavier container slides outward off the turntable; the lighter one stays on. • both containers slide off the turntable at the same turntable speed. • the lighter container slides inward. • the heavier container slides inward.

  5. Answer Now Evaluate the integral: . • ex – 9 ln (9 + ex) + C • ex + 9 ln (9 + ex) + C • 9ex– 9 ln (9 + e-x) + C • 9ex – ln (9 + e-x) + C
