Problem: Rank in order, from largest to smallest, the angular accelerations a to d in .

FREE Expert Solution

Angular acceleration is given by:

α=τI, where τ is torque and I is the moment of inertia. 

Torque is expressed as:

τ=rF, r is radius and F is force. 

Rotational inertia of an object is:

I=mr2, where m is mass. 

Therefore, angular acceleration is given by:

Problem Details

Rank in order, from largest to smallest, the angular accelerations a to d in The figure shows four particles on strings moving in horizontal circles. Particle, labelled as a, has a mass m and is moving in a circle of radius r under the tangential force F. Particle, labelled as b, has a mass 2 times m and is moving in a circle of radius r under the tangential force 2 times F. Particle, labelled as c, has a mass m and is moving in a circle of radius 2 times r under the tangential force F. Particle, labelled as d, has a mass 2 times m and is moving in a circle of radius 2 times r under the tangential force 2 times F..
