- I think rotational speed is wrongCalculate the rotational inertia of a wheel that has a kinetic energy of 14.8 kJ when rotating at 705 rev/min.Find the angular speed of a particle in rotational motion that has a linear (tangential) speed of 9 meters/second when traveling around a circle with a radius of 0.4 meters.
- What is the final speed in m/s of a solid cylinder that rolls down a 56.202 meter high ramp. The cylinder starts from rest and has a mass of 1.037 kg and a radius of 2.543 meters.Observe the link between linear and angular acceleration.A car is designed to get its energy from a rotating flywheel (solid disk) with a radius of 2.00 m and a mass of 400 kg. Before a trip, the flywheel is attached to an electric motor, which brings the flywheel's rotational speed up to 4500 rev/min. (a) Find the kinetic energy stored in the flywheel. (b) If the flywheel is to supply energy to the car as would a 20.0-hp motor, find the length of time the car could run before the flywheel would have to be brought back up to speed.
- Calculate rotational kinetic energy.find the angular speed of the disk after ten revolutions in rad/s?Starting from rest, a hollow ball rolls completely down a hill of height 3.5 meters. At the bottom the ball has an angular velocity of 20.2 rad/s. Calculate the radius of the ball. (Iball = (2/3)mr2) (Assume that no energy is lost due to nonconservative forces.)
