Question: The blades in a blender rotate at a rate of 7290 rpm. When the motor is turned off during operation, the blades slow to rest in 3.67 s. What is the angular acceleration as the blades slow down? The initial rotation is in the positive direction.

Think of angular motion the same as you think of linear motion, only instead of distance we have angles, instead of velocity we have angular ...

Solution Summary

This solution provides a detailed, step by step response which first conceptualizes how to approach understanding each of the variables used in angular acceleration problems. Secondly, this response constructs the equation which needs to be used to solve for the desired value and this is completed in a Word document.

The OTA's solution is attached. We both got an answer of 208 rad/s^2.

A 1.10 m-long massless rod is pivoted at one end and swings around in a circle on a frictionless table. A block with a hole through the center can slide in and out along the rod. Initially, a small piece of wax holds the block 10.0 cm from the pivot. The block is spun at 50.0 rpm, then the temperature of the rod is slowly increa

A merry-go-round makes 24 revolutions in a 3.0-min ride. (a) What is it's average angular speed in rad/s? (b) What are the tangential speed of two people 4.0 m and 5.0 m from the center, or axis of rotation?

1) Automobile engine slows down from 4500 rpm to 1200 rpm in 2.5 s. Calculate (a) its angularacceleration, assumed constant, and (b) the total number of revolutions the engine makes in this time.
2) Pilots can be tested for the stresses of flying high speed jets in a whirling "human centrifuge," Which takes 1.0 min to turn t

You are to design a rotating cylindrical axle to lift 800-N buckets of cement from the ground to a rooftop 78.0 m above the ground. The buckets will be attached to a hook on the free end of a cable that wraps around the rim of the axle; as the axle turns, the buckets will rise.
1. What should the diameter of the axle be in or

Could you please provide the answers and workings out to the following physics problems.
1. A wheel with a 0.10-m radius is rotating at 35 rev/s. It then slows uniformly to 15 rev/s over 3.0-s interval. What is the angularacceleration of a point on the wheel?
2. During the spin-dry cycle of a washing machine, the motor slo

Question: Bar BDE is attached to two links AB and CD. Knowing that at the instant shown link AB rotates with a constant angular velocity of 3 rad/s clockwise, determine the acceleration (a) of point D, (b) of point E.
