A solid sphere rolls in released from rest and rolls down an incline plane, which is 2.0 m long and inclined at a 30° angle from the horizontal. (a) Find its speed at the bottom of the incline. (Remember that the kinetic energy in rolling motion is the translational kinetic energy ½ Mv2 of the center, plus the rotational K.E. ½ Iω2 about the center. Also remember that v = ωr if the sphere rolls without slipping.) (b) Find the...

A 6-kg ball is released from rest and rolls down an incline.
When it reaches the end of the incline it falls through a height of
3 meters to reach a waiting cart.
How far from the base of the table should the waiting cart be
placed?
Essentially, how far away will the ball land from the base of
the table?

In a scene from a television show, a van rolls down an incline and off a vertical cliff, falling into a river below. The van starts from rest and rolls down the incline, which makes an gle of 24.0° below the horizontal, with constant acceleration of 3.82 m/s2. After rolling down the incline a distance of 40.0 m, it reaches the u edge of the cliff which is 30.0 m above the river. (a) How much time (in s) does...

A sphere ROLLS SMOOTHLY down the incline. What can we say for sure? 1.The normal force creates torque. 2.There is static friction and it creates torque. 3.The normal force cancel the weight. Therefore, the sphere rolls down the incline at constant speed. 4.There is kinetic friction and it creates torque. 5.The weight creates torque.
