A grinding wheel is initially rotating at 36 rad/s (radians per second) when its driving motor is turned off. If the wheel continues rotating at a constant rate of 3 rad/s^2, how long will the wheel take to rotate through an angle of 216 radians?
A platform rotating at 6.0 rad/sec slows down with constant angular acceleration and stops after 25s, what is the angular displacement of the platform? The answer is 30 radians but I keep getting a different answer.
the angular position of a point on a rotating wheel is given by theta=2+4t^2+3t^3 rad/s? or rotates at 84 rad/s in idle mode. When shut off, its angular acceleration is -29 (a) What is the angular velocity after 1.0 s? (b) How long will it take for the motor to completely stop? (C) How many revolutions does the motor make before stopping after it 15 turned off? 5.) The angular position of a point on a rotating wheel is given...
3. At t-0, angular velocity of a wheel is 24 rad/s, and its angular acceleration is 30 rad/s. (i) How much angle does the wheel turn through after 2 seconds of rotation? (ii) At t-2 sec., the wheel suddenly begins to undergo angular deceleration (negative angular acceleration) of 8.16 rad/s'. What additional time from t -2 secs, does it take the wheel to come to a stop? Hint: Use appropriate rotational kinematic equation to answer different parts of the question....
A disk I=1/2MR^2 rotating at 1.0 rad/s accelerates to 5.0 rad/s while turning 10 radians. What is the disk's angular acceleration?
an electric motor rotating a workshop grinding wheel at 1.04x10^2 rev/min is switched off. assume the wheel gas a constant negative angular acceleration of magnitude 1.92 rad/s^2. a) how long does it take the grinding wheel to stop and b) through how many radians has the wheel turned during the tine interval found in part a)?
A wheel, initially rotating at 80 rad/s, begin lally rotating at 80 rad/s, begins to slow as a result of a constant angular deceleration of 10 rad/sec2. After 10 sec. Find: (a) the angular velocity of the wheel, and (b) the angle (in degrees) through it rotates in this time.
A wheel is rotating at 15 rad/s. (Show all work) a)The angular acceleration of the wheel if it stops after 20 seconds. b)The angle through which the wheel rotates in coming to rest? c)The number of revolutions made by the wheel in coming to rest?
A wheel, initially rotating at 80 rad/s, begins to slow as a result of a constant angular deceleration of 10 rad/sec. After 10 sec. Find: (a) the angular velocity of the wheel, and (b) the angle (in degrees) through it rotates in this time.
In a popular game show, contestants give a large wheel a spin and try to win money and prizes. The wheel is given an initial rotational velocity and this movement slows down over time and the wheel eventually stops. One contestant gives the wheel an initial angular velocity of 1 rev/2 s. Because of friction, the wheel eventually comes to rest ( 3. 0 rad/s) in 6 s. Because the wheel's angular velocity is changing, there is an angular acceleration....
