II. Problem Solving. Solve each of the following problem. Show your solution in an orderly manner. In problems 2-6, start your solution with the free-body diagram #1. A basketball is shot from an initial height of 2.4 m with an initial speed v, = 12 m/s directed at an angle of 0, = 35° above the horizontal. (A) How far from the basket was the player of if he made a basket? (B) At what angle to the horizontal did the ball enter the basket? - 12 m/s 35 10 ft 24 m 3.05 m #2. Block B in Figure rests on a surface for which the static and kinetic coefficients of friction are 0.60 and 0.40, respectively. The ropes are massless. What is the maximum mass of block A for which the system is in equilibrium? 20 kg # 3. If a bicyclist of mass 65 kg (including the bicycle) can coast down a 6.5° hill at a steady speed of 6.0 km/h because of air resistance, how much force must be applied to climb the hill at the same speed (and the same air resistance)? # 4. The coefficient of kinetic friction between the 2.0 kg block in the Figure and the table is 0.30. What is the acceleration of the 2.0 kg block?
