The wheels of a skateboard roll without slipping as it accelerates at 0.25 m/s2 down an 95-m-long hill. If the skateboarder travels at 1.8 m/s at the top of the hill, what is the average angular speed of the 2.6-cm-radius wheels during the entire trip down the hill? Express your answer to two significant figures and include appropriate units.

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 solid sphere of mass 1.5 kg and radius 15 cm rolls without slipping down a 35° incline that is 7.9 m long. Assume it started from rest. The moment of inertia of a sphere is given by I = 2/5MR2. (a) Calculate the linear speed of the sphere when it reaches the bottom of the incline. (b) Determine the angular speed of the sphere at the bottom of the incline.

Two spheres of equal mass M and equal radius R roll down an
inclined plane as shown in the figure. One sphere is solid and the
other is a hollow spherical shell. The plane makes an angle ? with
respect to the horizontal. The spheres are released simultaneously
from rest at the top of the inclined plane and they each roll down
the incline without slipping.
The total distance each sphere rolls down the ramp (the
hypotenuse) is d. There...
