2011-04-20 · A 33.0 kg child takes a ride on a Ferris wheel that rotates four times each minute and has a diameter of 24.0 m. (a) What is the centripetal acceleration of the child? (b) What force (magnitude and direction) does the seat exert on the child at the lowest point of the ride? magnitude? direction?
http://hyperphysics.phy-astr.gsu.edu/hbase/imgmec/ I = m R^2 = 28 * 1.03 ^2 = 29.7052 kg m 2. ω = 280 / 60 * 2π= 29.3215 rad /s. The work needed to stop the wheel will be the same as the rotational kinetic energy of the wheel it needs to lose. 2010-11-30 · Favorite Answer. Change in Kinetic energy is Work. So, K=1/2Iw^2 (w is angular speed) w is given and is 29.32153143 rads/s.
How much work must be done to stop it? What is the required average power?

The rotational inertia of a cylindrical disk is given by I = 1 2 MR2 I = 1 2 24.8 kg( 0.233 m)2 I = 0.673 kg ·m2 (b) When the grinding wheel’s motor is turned off, friction causes the wheel to slow from 1200 rpm to rest in 59.8 s. It turns out that the kinetic energy associated with rotation in a wheel is proportional to the wheel's rotational mass. To show you that, I'm going to get my second wheel.
It must be brought to a stop in 29.0 s. (a) How much work
A bicycle wheel has a radius R = 32.0 cm and a mass M = 1.82 kg which you may assume to be concentrated on the . trigonometry.
