A person of mass 76 kgkg stands at the center of a rotating merry-go-round platform of radius 3.5 mm and moment of inertia 900 kg⋅m2kg⋅m2 . The platform rotates without friction with angular velocity 0.90 rad/srad/s . The person walks radially to the edge of the platform.     Part A Calculate the angular velocity when the person reaches the edge. Express your answer using three significant figures and include the appropriate units.

The angular speed of a propeller on a boat increases with constant acceleration from 14 rad/srad/s to 35 rad/srad/s in 2.6 revolutions. Part A What is the angular acceleration of the propeller?         Express your answer in radians per second squared.

I need help with this problem. Thanks

A rotating door is made from four rectangular glass panes, as shown in the figure. The mass of each pane is 94.8 kg. A person pushes on the outer edge of one pane with a force of F = 71.7 N that is directed perpendicular to the pane. Determine the magnitude of the door's angular acceleration. 1.2 m 1.2 m Number i Units

Case 1: A DJ starts up her phonograph player. The turntable accelerates uniformly from rest, and takes t1 = 11.6 seconds to get up to its full speed of f1 = 78 revolutions per minute. Case 2: The DJ then changes the speed of the turntable from f1 = 78 to f2 = 120 revolutions per minute. She notices that the turntable rotates exactly n2= 12 times while accelerating uniformly.  a. Calculate the magnitude of the angular acceleration of the turntable (in radians/second2) while increasing to 120 RPM (Case 2).  b. How long (in seconds) does it take for the turntable to go from f1 = 78 to f2 = 120 RPM?

Case 1: A DJ starts up her phonograph player. The turntable accelerates uniformly from rest, and takes t1 = 11.6 seconds to get up to its full speed of f1 = 78 revolutions per minute.Case 2: The DJ then changes the speed of the turntable from f1 = 78 to f2 = 120 revolutions per minute. She notices that the turntable rotates exactly n2= 13 times while accelerating uniformly. a. Calculate the angular speed described in Case 1, given as f1 = 78 revolutions per minute, in units of radians/second. b. How many revolutions does the turntable make while accelerating in Case 1? c. Calculate the magnitude of the angular acceleration of the turntable in Case 1, in radians/s^2. d. Calculate the magnitude of the angular acceleration of the turntable (in radians/s^2) while increasing to 120 RPM (Case 2). e. How long (in seconds) does it take for the turntable to go from f1 = 78 to f2 = 120 RPM?

n A golfers clubs' linear tangential velocity at contact with the ball on the tee was recorded as 42.4 m/s. Given the distance from the club head to the golfers centre of rotation as 1.58 m calculate the angular velocity (radians/s) of rotation at the point of contact to 2 decimal places. s page Answer: e here to search 18 W 8 N g P Finish attempt...
