3 part question about angular/tangential acceleration

AI Thread Summary
The discussion revolves around a homework assignment involving a merry-go-round, where a child’s acceleration, the horizontal force of friction, and the minimum coefficient of static friction need to be calculated. The merry-go-round completes one revolution in 15.7 seconds, and the child is positioned 4.3 meters from the center, with a mass of 53.1 kg. Participants express frustration over the lack of relevant formulas taught by the instructor, impacting their ability to solve the problems. The conversation encourages collaboration, with a focus on developing a plan to arrive at the solutions. Overall, the thread highlights the challenges faced by students in understanding angular and tangential acceleration concepts.

Homework Statement



Hi all,
Assignment due at midnight ET, these are the last questions I'm missing
1. A merry-go-round makes one complete revolution in 15.7 s. A 53.1 kg child sits on the horizontal floor of the merry-go-round 4.3 m from the center. Find the child’s acceleration. The acceleration of gravity is 9.8 m/s^2 . Answer in units of m/s^2 .
2. Find the horizontal force of friction that acts on the child. Answer in units of N.
3. What minimum coefficient of static friction is necessary to keep the child from slipping?

Homework Equations

The Attempt at a Solution


Teacher did not attempt to teach us any relevant formulas for this unit. It's pretty sad.

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
