A6 kg penguin gets onto a ferris wheel, with a radius of 5m, and stands on a bathroom scale. the wheel starts rotating with a constant acceleration of .001 rad/s2 for two minutes and then runs at a constant angular velocity. after the wheel is rotating at a constant rate, what is the penguin’s a) angular momentum about the center of the ferris wheel, b) tangential velocity c) maximum & minimum readings on the bathroom scale (and where do they occur? )

Part a)

Part b)

Part c)

Explanation:

As we know that Ferris wheel start from rest with angular acceleration

time taken = 2 min

so here we have its angular speed after t = 2min given as

Part a)

Angular momentum of the Penguine about the center of the wheel is given as

Part b)

tangential speed is given as

Part c)

Maximum reading of the scale at the lowest point is given as

Minimum reading of the scale at the top point is given as

explanation:

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
