A mass hanging from a spring oscillates with a period of 0.35 s. Suppose the mass and spring are swung in a horizontal circle, with the free end of the spring at the pivot. What rotation frequency, in rpm, will cause the spring's length to stretch by 25%? Express your answer in revolutions per minute. ► View Available Hint(s) frot = VE ΑΣΦ 85.715 ? rpm

A turntable rotates at 45 rev/min. Calculate the angular velocity of the turntable. A particle on the turntable is located 0.13 m from the center of the rotating turntable. What is the speed of the particle? The particle on the turntable has a mass of 3 g. Calculate the force of friction which keeps it from sliding off.

A wheel is turning at 55 rad/s, and is slowing due to friction at a rate of -1.7 rad/s^2. a.) how long will the wheel turn before coming to rest?____ s (2 significant figures-round to the ones place) b.) how far will the wheel turn before coming to rest? ____radians (2 significant figures- round to the tens place)

A 25.8 kg kid hops on, 1.40 m from the axis. What is the new angular velocity? [?] rad/s Hint: The kid is not part of the merry-go- round. Find his I separately, and add it. ght 2003-2003 International Academy of Science. All Rights Reserved. Q Search G B H N K Enter L
