- A frisbee’s stability is maintained by its angular momentum. A 175gram frisbee with a diameter of 12inchesis thrown with an angular velocity of 5rev/s . Assume the frisbee can be modeled as a flat solid disk. Find the magnitude of the angular momentum vector.PLEASE SOME ANSWER THIS ASAP AND SHOW ALL THE WORK PLS A merry-go-round in a playground (spinning horizontal disk) of mass M and radius R is initially rotating inthe x/y plane at a constantω0around a fixed vertical axis through the middle of the disk. A girl of mass m runstowards italong a path that is tangent to the rim and then jumps on the rim and holds on. The disk spinsfasterafter she jumps on. Treat the girl as a point mass.a) Choose one: Which of the following is conserved for the disk+girl system before and after she jumps on? (i) mechanical energy, ii) angular momentum, iii) linear momentum. iv) 2 or more of the above. b) Draw an overhead sketch of the disk with the disk rotating such that ω0 is in the +z direction (out). Show thevelocity vector of thegirl right before she jumps on. Solve for the necessary speed v that she must have in order for the disk to tripleits angular velocity after she jumps on. Your expression should depend on ω0, m, M, andR. Simplify it as much as…Asmall cube (M = 0.45 kg) is at a height of 315 cm up a frictionless track which has a loop of radius, R= 47.25 cm at the bottom.

Calculate the maximum height it can reach before coming to stop.Let’s approximate the motion of a yo-yo with that of a solid cylinder with a string wrapped around it. The string has alength of 1.2 m and the cylinder has a mass of 0.1 kg and a radius of 0.05 m. Suppose the cylinder was released atrest from the top, what would be its velocity when it reaches the bottom?Help me please is for today!! The two forces that can be replaced by an equivalent force R that acts at point B on the beam. Determine the distance b that B locates (suggestion the combined moment of the two forces with respect to any point is equal to the moment of R with respect to the same point)
