The three classes of levers can be found in your body. Use diagrams A, B, and C to answer the questions below. Also label the effort input force), fulcrum and load output force) on each diagram . LEVER B 3. Type of Lever : 4. How is this lever used in the body ?

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
