Question

an object on an inclined ramp of mass 1.39kg. The angle of the inclined surface is 29deg with the horizontal. The object on the ramp is connected to a second object of mass 2.17kg on a horizontal surface below an overhang that is formed by the inclined surface. Further, an external force of magnitude 9.00N is exerted on the object on the ramp. We observe both objects to accelerate. Assuming that the surfaces and the pulley are frictionless, and the connecting string and the pulley are massless, what is the tension in the string connecting the two objects?

Answer 1

m1•a=F-T-m1•g•sinα
m2•a=T
(m1+m2)a= F-T-m1•g•sinα+T
a=(F-m1•g•sinα)/(m1+m2).
T=m2•a=m2• (F-m1•g•sinα)/(m1+m2)=...
