A person sits in a chair that is free to rotate without friction. Intheir hands, they hold two masses: Mass m1 = 5.0 kg a distance r1 = 0.35m from their body and mass m2 = 3.0 kg a distance r2 = 0.75 m from their body. a. At what distance r1 should the person hold mass m1 if they want to change their rotation speed from w1 = 8.0 rad/s to wf = 5.0 rad/s? b. What is the new moment of inertia about the vertical axis when m1 is held at this new distance?
In the figure, a solid 0.1 kg ball rolls smoothly from rest (starting at height H = 6.3 m) until it leaves the horizontal section at the end of the track, at height h = 2.0 m. How far horizontally from point A does the ball hit the floor? Number Units
On a carnival ride, you stand next to a wall of a circular drum which spins around the center. When drum is spinning fast enough the floor drops away and you remain stuck to the wall and do not slide down to the floor until the drum slows down some. Assume a rider has a mass of 55.0 kg, and the drum has a radius of 6.00 m. The average linear speed that a rider is traveling with around the drum is 7.80 m/s. What is the normal force that the drum is exerting on the rider to keep her from sliding down to the floor?
An angular velocity of 10 rad/s is how many revolutions per minute (RPM)? Which is the answer ? 0.535 RPM 6.28 RMP 27.2 RMP 377 RMP 95.5 RMP
A ball of radius 0.200 m rolls with a constant linear speed of 3.89 m/s along a horizontal table. The ball rolls off the edge and falls a vertical distance of 2.10 m before hitting the floor. What is the angular displacement of the ball while the ball is in the air? 0 = i
A small 700 g ball on the end of a thin, light rod is rotated in a horizontal circle of radius 2.5 m. Calculate the torque needed to keep the ball rotating at a constant angular speed if the air resistance experienced by the ball is 0.0200 N. Ignore the rods moment of inertia and air resistance. Hint: Treat the small ball as a particle.
