Got it! :D θ = 180 deg *(pi/180) = 3.14 rad ω = 26.07 θ = ωt which turns into t = θ/ω t = .12044

A gymnast is performing a floor routine. In a tumbling run she spins through the air, increasing her angular velocity from 2.90 to 5.40 rev/s while rotating through one half of a revolution. How much time does this maneuver take? Knowns: w0 = 2.9 rev/sec * 2pi rad = 18.22 rad/sec w = 5.4...

A CD has a playing time of 74.2 minutes. When the music starts, the CD is rotating at an angular speed of 488 revolutions per minute (rpm). At the end of the music, the CD is rotating at 215 rpm. Find the magnitude of the average angular acceleration of the CD. Express your answer in rad/s^2...

Got it! Thank you

Two friends, Al and Jo, have a combined mass of 151 kg. At an ice skating rink they stand close together on skates, at rest and facing each other, with a compressed spring between them. The spring is kept from pushing them apart, because they are holding each other. When they release their arms...
