00-64 Figure 5-56 shows a box of mass m2 = 1.0 kg on a friction- less plane inclined at angle θ= 30°. It is connected by a cord of negligible mass to a box of mass m 3.0 kg on a horizontal fric- tionless surface. The pulley is frictionless and massless. (a) If the magnitude of horizontal force F is 2.3 N, what is the tension in the connecting cord? (b) What is the largest value the magnitude of F...
Block A in the figure has mass mA = 4.20 kg, and block B has mass mB = 2.40 kg. The coefficient of kinetic friction between block B and the horizontal plane is μk = 0.520. The inclined plane is frictionless and at angle θ = 34.0°. The pulley serves only to change the direction of the cord connecting the blocks. The cord has negligible mass. Find (a) the tension in the cord and (b) the magnitude of the acceleration...
1. The figure shows a box with mass m1 on a frictionless plane inclined at angle ?1. The box is connected via a cord of negligible mass to another box with mass m2 on a frictionless plane inclined at angle ?2 (> ?1). The pulley is frictionless and has negligible mass and assumes that the setup is on the surface of the earth. a) Provide free-body force diagram for both boxes. b) What is the acceleration in terms of m1,...
The figure below shows a box of dirty money (mass m1 = 5.5 kg) on a frictionless plane inclined at angle θ1 = 35°. The box is connected via a cord of negligible mass to a box of laundered money (mass m2 = 2.0 kg) on a frictionless plane inclined at angle θ2 = 55°. The pulley is frictionless and has negligible mass. What is the tension in the cord?
Kindly help me In the figure, a force of magnitude 15 N is applied to a FedEx box of mass m2 1.2 kg. The force is directed up a plane tilted by θ-31°. The box is connected by a cord to a UPS box of mass m1 2.9 kg on the floor. The floor, plane, and pulley are frictionless, and the masses of the pulley and cord are negligible. What is the tension in the cord? mg 耀1 In the...
The figure below shows an object of mass m1 = 1.0 kg on an inclined surface. The angle of the inclined surface is θ = 30° with the horizontal. The object m1 is connected to a second object of mass m2 = 2.5 kg on a horizontal surface below an overhang that is formed by the inclined surface. Further, an external force of magnitude Fext = 10 N is exerted on the object with mass m1. We observe both objects...
The figure shows a container of mass m2 = 2.6 kg connected to a block of mass m2 by a cord looped around a frictionless pulley. The cord and pulley have negligible mass. When the container is released from rest, it accelerates at 0.88 m/s2 across the horizontal frictionless surface. What are (a) the tension in the cord and (b) mass m2?
