- The y-component of the force F which a person exerts on the handle of the box wrench is known to be 66 lb. Determine the x-component and the magnitude of F.Two blocks, M1 and M2, are connected by a massless string that passes over a massless pulley as shown in the figure. M2, which has a mass of 25.0 kg, rests on a long ramp of angle ?=25.0∘. Friction can be ignored in this problem. Determine the mass ?1 of block M1 for which the two blocks are in equilibrium (no acceleration). If the actual mass of M1 is 5.00 kg and the system is allowed to move, what is the acceleration ? of the two blocks? A positive acceleration corresponds to M2 moving up the incline. What distance ? does block M2 move in 2.00 s?Consider a 100-N weight suspended by two wires as shown in theaccompanying figure. Find the magnitudes and components of theforce vectors F1 and F2.
- There are two forces on the 1.19 kg box in the overhead view of the figure but only one is shown. For F1 = 15.7 N, a = 14.7 m/s2, and θ = 34.1°, find the second force (a) in unit-vector notation and as (b) a magnitude and (c) a direction. (State the direction as a negative angle measured from the +x direction.)What is the tension in the upper rope at point B ? At the zoo, two monkeys weighing 24.0 N each are playing on a rope-and-pulley system. If the lower rope is attached to a weight of mass m = 18.0 kg. What is the tension in the upper rope at point B?Two masses m1=5.5 kg and m2=2.5 kg attached at the two ends of a string in a pulley that has friction. Given the kinetic frictional coefficient between the string and the pulley is 0.11. Calculate the acceleration of the block.
- In the diagram shown, mass 1 (m1) is 18.79 kg and the coefficients of static and kinetic friction are 0.31 and 0.18, respectively. What is the maximum mass that mass 2 (m2) can have for the system to remain at rest? Assume that the pulley shown is ideal, massless, and frictionless. m2 = kgTwo forces F1 and F2 act on a 5.00-kg object. Taking F1 = 20.0 N and F2 = 15.0 N, find the accelerations of the object for the configurations of forces shown in parts (a) and (b) of Figure P4.7. Figure P4.7The masses of the red and green boxes are 8.92 kg and 2.5 kg, respectively. If the red box is pushed by 17.6 N force, the magnitude contact force (N) the system is
- A 58 kg circus performer hangs from a bar suspended from a ceiling as shown in the figure. If the bar masses 12 kg (and its weight acts at its center) and has a length of1.4 m, what is the tension T2 in the rope? (The rope is attached 0.85 m along the bar).A cord passing over a pulley connects two masses, as shown, where m1 = 3.60 kg and m2 = 6.50 kg. Assume the pulley and surfaces are frictionless, and the cord is massless and does not stretch. (Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.) A triangular structure is oriented such that its base rests upon a horizontal surface. Its left and right sides are of equal length and and each form 35.0° inclines with respect to the base. Rectanglular masses labeled m1 and m2 are positioned, respectively, on the structure's left and right inclines. The two masses are connected by a cord that passes over an upright pulley affixed to structure's apex. (a) What is the acceleration of each block? (Enter the magnitude in m/s2.) m/s2 (b) What is the tension in the cord (in N)? NThe masses of the red and blue wagons are 6.09 kg and 2.63 kg, respectively. If the red wagon is pulled by 18.9 N force, the tension (N) in the cable connecting the two wagon of the system is:
