Problem 3: (15 points a lazy susan (a circular disk mounted on a vertical axle) is at rest at -0. it has frictionless bearings. texas sized cockroach of mass m starts center with velocity dp a) find the direction of spinning and moment of inertia of the lazy susan about the central axis (note that mass of lazy susan and its radius are not given). running counterclockwise around a circle distance d from the velocity of vo relative to the ground. as a result, the lazy susan starts spinning with angular top view axle wise spiuniu b) the cockroach finds a bread crumb and stops. what is the angular velocity of the lazy susan after the cockroach stops?

An alligator swims to the left with a constant velocity of 5 \,\dfrac{\text{m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction. when the alligator sees a bird straight ahead, the alligator speeds up with a constant acceleration of 3 \,\dfrac{\text {m}}{\text s^2}3 s 2 m ? 3, space, start fraction, m, divided by, s, start superscript, 2, end superscript, end fraction leftward until it reaches a final velocity of 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction leftward. how many seconds does it take the alligator to speed up from 5 \,\dfrac{\text {m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction to 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction?

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
