1) An object rotating at 500 rpm (rev/min) is spinning faster than an object rotating at 500 rad/s. True False 2) If you're goin to calculate an object's tangenital velocity from its angular velocity, the angular velocity can be expressed in either rad/s or rev/min True false 3) Tangential acceleration is measured in m/s^2 true false

An electric saw uses a circular spinning blade to slice through wood. When you start the saw, the motor needs 5.00 seconds of constant angular acceleration to bring the blade to its full angular velocity. If you change the blade so that the rotating portion of the saw now has 2.00 times its original rotational mass, how long will the motor need to bring the blade to its full angular velocity? Answer: T2 =? seconds

An object is spinning with an initial velocity of 17.5 rad/s. Over a time of 1.45 s, the object increases its angular velocity to 39.8 rad/s. What angular acceleration did the object undergo during that time?

The tip of a spinning flagella moves in a circular path and has a initial angular velocity of +1.38 Hz and an angular acceleration of +2.91 s-2. After 2.3 s of motion, determine the magnitude of the displacement (not the tangential displacement) of the tip of the flagella if the radius of it's path is 34 nm. For simplicity, you may wish assume that the tip of the flagella initially begins on the x-axis. Report your answer in nm.

A spinning basketball is rotating clockwise at 5 revolutions/s. At 3 seconds, a player puts their hand on the ball and slows it down to a stop in one second. A.) What is the acceleration the player applied to the ball? B.) What is the total angular distance in degrees of the ball including the initial spinning and the angular distance while it was slowing? Please show all equations used and all your work.
