In Fig. each of the suspended blocks has weight w. The
pulleys are frictionless, and the ropes have negligible weight. In each
case, draw a free-body diagram and calculate the tension T in the rope
in terms of w.

- Subject: physI created a free body diagram but need help explaining how the slope of the ramp can be used to determine the coefficient of friction. Im trying to use math to exaplain using μ = tan(θ) and my rise is 15cm and my run is 55cm. My teacher taught us SOH CAH TOA but im not sure how I would expalin using math. Please help me out!What is the max mass block m can be without moving? I would suggest an x & y table in which we can add all the forces up and equal them to ma. Please and thank you.

If the object then comes to a stop over a time of 4.23 seconds, what must the coefficient of kinetic be? Assume that only friction, the normal force, and the force due to gravity are acting on the mass. Enter a number rounded to 3 decimal places.
- An elevator weighs 10000N. It has a cord attached to it on the top. It accelerates downward at 3m per second squared, what’s the tension?A box of mass 5 kg is at rest on a rough plane inclined at an angle of 40° to the horizontal. Calculate the magnitude of the friction force, in newtons, to two significant figures. (Take the magnitude of the acceleration due to gravity, g. to be 9.8 ms 2.) The magnitude of the friction force is N (to 2.s.f.).A rope is strung between two walls parallel to the floor. A 35kg mass is hung from the rope at its midpoint. This causes the rope to sag by 12°. Find the tension in the rope. Image is what I have so far... I'm stuck!! Please let me know what I'm doing wrong
