In a skating jump, a skater rotates around their vertical central axis. Duringthe jump, the skater's rotation rate is increased by bringing their arms intotheir side. a) When bringing their arms into their side, do es the rotational kinetic energyof the skater go up, go down or stay the same? If it changes, where do es theenergy for this change come from or go to? b) Show that the change in rotational kinetic energy of the skater ∆KR canb e found by (see image) here KRi is the initial rotational kinetic energy of the skater, ωf is the nalangular sp eed and ωi is the initial angular speed. c) During the jump, when the skater draws their outstretched arms inwards,what total torque is acting on the skater if their final rate of rotation is tworotations p er second? d) After landing again, the skater is able to stop rotating and come to acomplete standstill in 0.7s. What is the average ratio of the torque on theskater to the skater's total moment of inertia during the time they come to…

DYNAMICS OF RIGID BODIES UPVOTE WILL BE GIVEN.PLEASE WRITE THE COMPLETE SOLUTIONS CORRECTLY AND LEGIBLY. NO LONG EXPLANATION NEEDED. BOX THE FINAL ANSWER. The acceleration of a particle moving horizontally under rectilinear motion is defined by the relation a=9t2-3.3t where a is in ft/s2 and t is in s. Initially, the particle is moving at 5ft/s and started at x=5.8 ft. Determine the velocity of the particle at t=3.1s. Round off only on the final answer expressed in 3 decimals. Indicate appropriate units.
The plot below shows the acceleration of a mass placed at the end of a beam as it oscillates: 20 Which we model as: Acceleration (m/s²) 15 10 5 0 -5 -10 -15 -20 0.5 1 Wd 1 1.5 1 2 = wn√1 y(t) = Ae-3wnt sin(wat) y(t) = Ae-Ct sin 1 2.5 Time (s) = 2π T 2π T 1+ 3 2π We will use MATLAB to find the decay constant C and the period T. We can then use these to calculate the damping ratio and the natural frequency @n, using: 3.5 T 4 2 and C = {wn O data zeros peaks decay fit 4.5 Using the information above, derive the expression shown below for the damping ratio 3. 1 3 = 5
