hi,
could some one please explain where i am wrong?
A mass M of 5.80E-1 kg slides inside a hoop of radius R=1.50 m with negligible friction. When M is at the top, it has a speed of 4.43 m/s. Calculate the size of the force with which the M pushes on the hoop when M is at an angle of 46.0°.
i guess what i need to find is the difference between the perpendicular to the hoop component of mg and the centr. force. the centr. force needs the v in that point
which i can find using energy conservation.
i get the wrong answer. i think i am not wrong calculating. maybe what i am asked is not
what i end up calculating
thanks
