Acceleration force
Three objects are connected on an inclined table as shown in the diagram below. The objects have masses 8.0 kg, 4.0 kg and 2.0 kg as shown, and the pulleys are frictionless. The tabletop is rough, with a coefficient of kinetic friction of 0.47, and makes an angle of 20.0° with the horizontal.
a. free body diagram b. Determine the acceleration and direction of motion of the system. c. Determine the tensions in the two cords.
a. Free body diagrams
The forces acting on the block of mass m1= 8.0 kg are the tension in the thread T1 vertically upward and the weight of the block m1 g (g is the acceleration due to gravity = 9.8 m/s2) vertically ...
Solution Summary
The three objects which are connected on an inclined table is determined.
Four problems on dynamics.
Please see attachment for fig.
24. Pictures below (see attachment) show the loads hanging from the ceiling of an elevator that is moving at constant velocity. Find the tension in each of three strands of cord supporting each load.
26. Angle phi =15 degree. Assuming the block start from the rest at the top and that the leghth of the incline is 2m. Find
a) Acceleration of the block
b) its speed when it reaches the bottom of the incline
28. 5.00 kg object placed on frictionless, horizontal table is connected to a cable that passes over a pulley and then is fastened to a hanging 9.00kg object as shown below (see attachment). Draw free body diagram of both. Find the acceleration of both objects and tension in the string?
54. 2 blocks of mass 3.5Kg and 8.0Kg are connected by a massless string that passes over a frictionless pulley. The inclinces are fictionless. Find
a) The magnitude of acceleration of each block
b) The tension in the string
