A solid spherical ball of mass 1.72 kg and radius 0.16 m rolls along a smooth, level surface with a speed of 2 m/s. What is the ball
moment of Inertia of sphere, I = (2/5)*m*R^2
= 0.4*1.72*0.16^2
= 0.0176 kg.m^2
angular speed, w = V/r
= 2/0.16
= 12.5 rad/s
Rotational KE = 0.5*I*w^2
= 0.5*0.0176*12.5^2
= 1.375 J

2) A solid uniform ball of mass m and radius r rolls down a hemispherical bowl of radius R, starting from a height h above the bottom of the bowl. The surface on the left half of the bowl has sufficient friction to prevent slipping, and the right side is frictionless. R (a) (5 marks) Determine the angular speed w the ball rotates in terms of e', when it rolls without slipping. (b) (5 marks) Derive an expression for the...
Problem 4. A solid sphere of mass m and radius r rolls without slipping along the track shown below. It starts from rest with the lowest point of the sphere at height h 3R above the bottom of the loop of radius R, much larger than r. Point P is on the track and it is R above the bottom of the loop. The moment of inertia of the ball about an axis through its center is I-2/S mr. The...
A uniform hollow spherical ball of mass 1.75 kg and radius 40.0 cm rolls without slipping up a ramp that rises at 30.0° above the horizontal. The speed of the ball at the base of the ramp is 2.63 m/s. How do we know that acceleration of the ball is constant considering newtons second law of motion? we are not allowed to use conservation of energy. We are only to use newtons second law for rotation
