A 9.00-kg hanging weight is connected by a string over a pulley to a 5.00-kg block that is sliding on a flat table (Fig. P5.24). If the coefficient of kinetic friction is 0.200, find the tension in the string. 5.00 kg 9.00 kg Figure

5. A 3.00 kg mass is initially at rest at the bottom of an incline of 35.0°. An applied force begins acting on the mass, pushing it up the incline with a constant force of 25.0 N, directed parallel to the incline. a) If the acceleration produced is 2.50 m/s? up the incline, what must the coefficient of kinetic friction be? b) If the applied force acts for 2.00 s, how far up the incline will the mass travel upon coming to rest? Measure this from where the applied force starts acting to where the mass comes to a stop.

– 3. A 64.3 kg skydiver jumps out of an airplane with a parachute. She decides not to pull the rip cord until she reaches terminal velocity. If the resistive force proportionality constant is 2.35 kg/s, what is the magnitude of the velocity when she decides to pull the cord? (Assume the drag force is proportional to the speed.) - a. 16.4 m/s b. 268 m/s c. 151 m/s d. 9.80 m/s e. 27.4 m/s

9. Two blocks are positioned on surfaces, each inclined at the same angle of 58.3 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 3.66 kg, and the coefficient of kinetic friction for both blocks and inclines is 0.460. Assume static friction has been overcome and that everything can slide. What is must be the mass of the white block if both blocks are to slide to the LEFT at an acceleration of 1.5 m/s^2?     2.16 kg     9.99 kg     6.02 kg     3.06 kg
