2 masses, pulley on a frictionless incline
posted by Natasha on .
an object of mass m1= 311 g on an inclined surface. The angle of the inclined surface is θ = 40o with the horizontal. The object m1 is connected to a second object of mass m2 = 355 g on the adjacent horizontal surface. Further, an external force of magnitude ІFextІ = 3.6 N is exerted on the object of mass m1. We observe both objects to accelerate. Assuming that the surfaces and the pulley are frictionless, and the pulley and the connecting string are massless, what is the tension in the string connecting the two objects?
The pulley is at the bottom of incline
It is not clear to me which way the incline is, and which direction the external force is acting.
Two masses are connected by a light string passing over a light, frictionless pulley as in Figure P5.52. The 5.00 kg mass is released from rest at a point 4.00 m above the floor.
(a) Determine the speed of each mass when the two pass each other.
(b) Determine the speed of each mass at the moment the 5.00 kg mass hits the floor.
(c) How much higher does the 3.00 kg mass travel after the 5.00 kg mass hits the floor?
