A solid spherical ball of mass 2.6 kg and radius 0.09 m rolls along a smooth, level surface with a speed of 2 m/s. The ball rolls up an inclined plane. How far up, vertical height, the plane does the ball go? Express your answer as the vertical height from the level surface.
4. A steel ball has a mass of 4.0 kg and rolls along a smooth, level surface at 62 m/s (b) At first, the ball was at rest on the surface. A force acted on it through a distance of 22 m to give it the speed of 62 m/s. What was the magnitude of the force?
A solid uniform spherical ball of mass 2.0 kg and radius 0.50 m rolls without slipping down a ramp that makes a 15 degree angle with the horizontal. What is the center-of-mass speed (in m/s) of the ball after it rolls 0.50 m down the ramp? A) 1.8 B) 2.5 C) 4.5 D) 7.0 E) None of these
A solid cylinder has mass 1 kg and radius 5 cm. If it rolls without slipping along a level surface at linear speed 2 m/s, what is its total kinetic energy?
Problem -2 A hollow ball of radius 0.5 m and mass 4.5 kg is rolling without slipping on a level surface at a constant speed of 4.0 m/s. The ball rolls up a 40- ramp and eventually stops before rolling back down. (the moment of inertia of a hollow ball of mass M and radius RisMR2) Find: (a) the angular (rotational) speed of the ball (in rad/sec) just before it begins to move up the ramp: (b) the rotational kinetic...
Problem #2 A hollow ball of radius 0.5 m and mass 4.5 kg is rolling without slipping on a level surface at a constant speed of 4.0 m/s. The ball rolls up a 40° ramp and eventually stops before rolling back down. (the moment of inertia of a hollow ball of mass M and radius R is MR2) Find: (a) the angular (rotational) speed of the ball (in rad/sec) just before it begins to move up the ramp; (b) the...
A hoop with mass, M, and radius, R, rolls along a level surface without slipping with a linear speed, v. What is the ratio of rotational to linear kinetic energy? (For a hoop, I = MR2.)
A solid ball with m=1.6 kg and radius 3.8 cm rolls a distance 9.2 m down a ramp that is inclined by an angle 22.2° with respect to the horizontal. At the bottom of the ramp, what is its rotational kinetic energy? The answer is 15.59 J but i'm unsure how to arrive at this.
