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
A solid, uniform sphere of mass 2.0 kg and radius 1.7 m rolls without slipping down an inclined plane of height 2.9 m. What is the angular velocity of the sphere at the bottom of the inclined plane?
1) A solid ball of mass M and radius R rolls without slipping down a hill with slope tan θ. (That is θ is the angle of the hill relative to the horizontal direction.) What is the static frictional force acting on it? It is possible to solve this question in a fairly simple way using two ingredients: a) As derived in the worksheet when an object of moment of inertia I, mass M and radius R starts at rest...
A uniform hollow spherical shell of mass M and radius R rolls without slipping down an inclined plane. The plane has a length of L and is at an angle (theta). What is its speed at the bottom?
Bowling Ball. A bowling ball rolls without slipping up a ramp that slopes upward at an angle to the horizontal. Treat the ball as a uniform solid sphere of mass M and radius R, ignoring the finger holes. a) Draw the free-body diagram for the ball. Explain why the friction force must be directed up the ramp. b )What is the acceleration of the center of mass of the ball? c) What minimum coefficient of static friction is needed to...
A solid ball of mass 2.0 kg rolls down a hill of slope 38 degree without slipping. Find the acceleration of the ball’s center of mass, the frictional force between ball and ground, and the minimum coefficient of static friction needed to prevent slipping.
A solid disk (radius R=2.5 cm , mass M =0.35 kg) rolls without slipping down an 30 degree-incline. If the incline is 4.2 m long and the disk starts from rest, what is the linear velocity of its center of mass at the bottom of the incline (in m/s)?
