(Show all the steps please)

Rotational Dynamics: Four objects of equal mass start at the topof an inclined plane. A solid cylinder, a thin walled cylinder, asolid sphere, and a thin walled sphere. All objects start at rest.Starting at rest,

A) Write down the work energy theorem including both kineticenergy terms and all potential energy terms.

B) If all four objects are released at the same moment, how longdoes each take to reach the bottom of the incline plane?

C) Find the ratio of translational (linear) kinetic energy torotational kinetic energy for each object.

D) Compare the results of the race obtained in part a to theresults obtained in part b.

E) If the ramp is 20 m long and inclined at an angle od 20degrees, what is the angular speed of the solid cylinder at thebottom of the ramp.

F) What torque is required to achieve this final angularspeed?

A All the object are starting at rest so none of them have kinetic energy but only potential energy which is given as mgh where m is the mass of the respective object g is gravity and h is the height of the ramp Now as they start rolling    See Answer
