a ball swings in a vertical circle at the end of a rope 1.5m long. when the ball is 26.9 degrees past the lowest point on its way up, its total acceleration is -22.5i+20.2j. at that instant (b) determine the magnitude of its radial acceleration
isnt the magnitude of Ar... +20.2m/s^2 ? The answer key says otherwise.
i really need someone to explain this concept to me... radial acceleration causes a change in magnitude... and A = Ar + At right? so why isn't the Magnitude of Ar... the vertical component of A in this question .
Please explain how i can find the magnitude of radial acceleration using trig.
thanks in advance
