Determine the magnitude of its maximumradial acceleration

AI Thread Summary
To determine the maximum radial acceleration of a discus thrown by an athlete, the relevant formula is aradial = v²/r, where v is the maximum speed (18.7 m/s) and r is the radius of the circular path (1.19 m). By substituting the given values into the formula, the radial acceleration can be calculated as aradial = (18.7 m/s)² / (1.19 m). This results in a maximum radial acceleration of approximately 285.5 m/s². The discussion emphasizes the importance of using the correct equations and provided values to solve for radial acceleration effectively. Understanding these concepts is crucial for accurately determining the dynamics of circular motion.

1. Before throwing a 0.821 kg discus, an ath-lete rotates it along a circular path of radius1.19 m. The maximum speed of the discus is18.7 m/s.Determine the magnitude of its maximumradial acceleration.Answer in units of m/s2



Homework Equations


atotal = sq rt (a2 radial + a2 tangential) where aradial = −v2/r and atangential = d|v|/dt


The Attempt at a Solution


I tried using the equation above but I don't think I have enough info or I don't know where the info goes

So you have aradial=v2/r

v= velocity and r= radius, both of which you are given.

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'

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...
