Which measure would not be useful to help you determine the change in angular velocity when the torque on a fishing reel is increased? the time it takes the line to unspool the amount of line that unspools the angular momentum of the fishing line the radius of the reel

A woman passes through a door with a tangential speed of 1.8 m/s from the center of the door, what is the door’s angular speed?

Suppose you're an field engineer inspecting an offshore wind turbine. You're in a boat approaching a the particular turbine you'll be inspecting. Your boat's velocity is a constant 8 knots on a course perpendicular to the turbine's axis of rotation. The turbine blades are 10 m in length and turning with a constant angular velocity of 20 rad/s. What additional information would you need in order to calculate the velocity of a point on the turbine blade tip relative to you? nothing, you have all the information you need turbine angular acceleration position of the blade tip relative to the turbine's rotation center at the time of measurement

Question 3:     Calculate the net torque (magnitude and direction) on the beam in Figure below about: (a) an axis through O perpendicular to the page; (b) an axis through C perpendicular to the page.

The diameters of the main rotor and tail rotor of a single-engine helicopter are 7.59 m and 0.98 m, respectively. The respective rotational speeds are 456 rev/min and 4143 rev/min. a) Calculate the speeds of the tips of both rotors. b) Compare these speeds with the speed of sound, 343 m/s.

James and Clare are riding their bicycles. They are riding at the same speed, but the tires on Clare’s bicycle are larger in diameter. Which wheels have the greater rotational (angular) speed? Why?

An orangutan leaps off of a cliff and its body begins to rotate clockwise. If the orangutan then starts to rotate both of its arms counter-clockwise, which of the following happens: The clockwise rotation of its body will be faster The clockwise rotation of its body will be slower The clockwise rotation speed of its body will not change Cannot say, not enough information provided

A bicycle tire of radius 0.43 m has a piece of gum stuck on its rim. What is the angle through which the tire rotates when the gum has moved through a linear distance of 1.86 m? Express your answer in radians and degrees.

Is the following statement true or false? Based on convention, a positive torque is the one that causes clockwise rotation; a negative torque is the one that causes counterclockwise rotation.

A bicycle tire rotates. What is true about a point A near the center and a point B near the rim?   Group of answer choices -Point B rotates with a faster angular velocity -they both rotate with the same angular velocity -they both rotate with the same tangential velocity -Point B rotates with a faster tangential velocity
