(11 points) A uniform solid sphere of mass m and radius r is placed inside a hemispherical bowl of radius R. The sphere is released from rest at an angle theta and rolls without slipping. (a) (6 points) Using Conservation of Energy, to find an expression for the angular speed of the sphere when it reaches the lowest point of the bowl. (b) (6 points) Find the magnitude of the centripetal acceleration of the center of mass of the sphere...

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 ball in the shape of a uniform spherical shell (like a soccer ball) of mass 1.5 kg and radius 15 cm rolls down a 35° incline that is 6.0 m high, measured vertically. The ball starts from rest, and there is enough friction on the incline to prevent slipping of the ball. (a) How fast is the ball moving forward when it reaches the bottom of the incline, and what is its angular speed at that instant? (b) If...

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 solid, uniform disk of radius 0.250 m and mass 53.2 kg rolls down a ramp of length 4.20 m that makes an angle of 15.0°with the horizontal. The disk starts from rest from the top of the ramp. (a) Find the speed of the disk's center of mass when it reaches the bottom of the ramp. m/s (b) Find the angular speed of the disk at the bottom of the ramp.

A marble of inertia m is held against the side of a
hemispherical bowl as shown in (Figure 1) and then released. It
rolls without slipping. The initial position of the marble is such
that an imaginary line drawn from it to the center of curvature of
the bowl makes an angle of 30? with the vertical. The marble radius
is Rm = 10 mm, and the radius of the bowl is Rb =
140 mm .

A small object oscillates back and forth at the bottom of a frictionless hemispherical bowl, as the drawing illustrates. The radius of the bowl is R, and the angle is small enough that the object oscillates in simple harmonic motion. Derive an expression for the angular frequency w of the motion. Express your answer in terms of R and g, the magnitude of the acceleration due to gravity. Hemispherical bowl R
