I am not quite sure what do you mean with confusion of radial and tangetinal acceleration. I know I acctually did not need the radial accel., but I needed the tangential to find the angular velocity ( ar= r *omega ^2) This is was actually only part I was not quite sure about. Is this...
Just remember to apply Newton second law. Which states that SUM F = ma.
Combining Hooke's law F = -kx and Newton law you can get your acceleration or in this case the gravity.
This is what I tried so far
Ui+Ki=Uf+Kf
mgh= (1/4 M(R squared) +m(r squared) +1/2m(V squared) +
I am not sure if this is complete since I can’t figure out if the dime has also final potential energy and also how to add the friction in this
I know for dime that n=mg and that...
Okay here is the problem.
A metal disk ( mass 250g , radius12 cm) is free to rotate about frictionless vertical axle through its center. The axle itself has negligible mass and a radius of 2 cm. A string wrapped around the axle passes over an ideal pulley to a hanging 85 g mass. A dime ( mass...
