AI Thread Summary
The discussion revolves around a physics homework problem involving a winch that raises two masses, 40kg and 10kg, with a frictional force of 60N acting on the heavier mass. The key tasks are to determine the force exerted by the winch for constant speed, and the tension in the cable when the masses are lowered or raised with an acceleration of 1.0 m/s². The equations set up include net force calculations for both masses, leading to results of 0.76 m/s² for acceleration and 482N for tension. A request for a visual aid to clarify the problem is mentioned, but there are issues with uploading the image due to size limits. The discussion highlights the importance of clear problem representation in physics.

Homework Statement


A winch raises a 40kg mass and a 10kg mass vertically up the side.A frictional force of 60N acting betweem the side and the 40kg mass.The angle the cable makes to the vertical is 15.
a)Find the force the winch must ecert on the cable to slide the mass at a constant speed up the side
b)If the mass are lowered with an acceleration 1.0m/s2, find the tension in the cable connecting the 2 mass
c)If the mass are raised with an acceleration of 1.0m/s2, find the tension in the cable connecting the 2 mass.


Homework Equations


Equations i got :
For mass 40kg : ma = T-Fg-Fk
For mass 10Kg: m2 a= F40g(of 40 kg) - Fg(10kg) -T


The Attempt at a Solution


(For mass of 40kg)
Fnet = T -F40g - Fk
ma = T-Fg-Fk

(For mass of 10kg)
Fnet = F40g - F10g
2 a= F40g(of 40 kg) - Fg(10kg) -T

Adding the eqations i got from relevant equations
a = 0.76m/s2 and T = 482N

A winch raises a 40kg mass and a 10kg mass vertically up the side.
What side? Is there a picture that goes with this?
 
ye there is a picture but when i try to upload from paint document it exceeds the space limit and i can't upload it.
 
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
