- 2.4 m B 30° plz help use g =9.8 The radius of a 6.2-kg wheel is 23.3 cm. The wheel is released from rest at point A on a 30-degree incline, as shown. The wheel rolls without slipping and moves 2.4 m to point B in 7.7 s. Determine the moment of inertia of the wheel. Express your answer in kg m², to at least a digit after the decimal point.ind the Angular speed (?) of a wind turbine turning at a rate of 85 revolutions per minute. Give Exact Answer with Correct Units for “Angular Speed (?) ”: Show formula Used:A history teacher is printing out papers with instructions for a class project. Let's assume the roller inside the printer turns with an angle 0 with the given which is e(t) = At^2 – Bt^3 Allow A be 2.50 + 0.07 rad/s^2 Allow B be s 0.450 ± 0.010 rad/s^3 Find the answers to the following questions.. 1) Find the angular speed of the roller at t = 1.00 s. 2) Find the uncertainty in the angular speed of the roller, if the uncertainty in time is given as 0.05s.
- A turn table starts from 12 rad/s of angular velocity and slows down to a stop in 10.0 s. Find the total angle turned during this time, in rad. Hint: use rotational kinematics formula. Assume initial angle and final angular velocity as zero. Your AnswerA merry-go-round on a playground consists of a horizontal solid disk with a weight of 795 N and a radius of 1.53 m. A child applies a force 50.5 N tangentially to the edge of the disk to start it from rest. What is the kinetic energy of the merry-go-round disk (in J) after 3.05 s? J Submit AnswerAll answers were incorrect and the solutions are confusing me. Please help! Also the 4th part of the question was not answered/explained
