Question

Question 2 A circular object (disc, hoop, sphere) of mass M and radius R rolls from rest, down a slope from a heighth above the ground as shown in the figure Masine The acceleration of the centre of mass is given by q sin асы - The force of static friction is given by Ng sine CMR Show that the friction where the moment of inertia for the rolling object is of the form does no work.

show that the friction is zero.
fs=(mgsin(teta))/(1+c^-1)

Answer 1

Dear student,

Find this solution, and RATE IT ,If you find it is helpful .your rating is very important to me.If any incorrectness ,kindly let me know I will rectify them soon.

Thanks for asking ..
