Atorsion pendulum is made from a disk of mass m = 7.1 kg and radius r = 0.71 m. a force of f = 42.4 n exerted on the edge of the disk rotates the disk 1/4 of a revolution from equilibrium.

Will give brainliest! jay rides his 2.0-kg skateboard. he is moving at speed 5.8 m/s when he pushes off the board and continues to move forward in the air at 5.4 m/s. the board now goes forward at 13 m/s.a. determine jay’s mass.b. determine the change in the internal energy of the system during this process.(express your answer to two significant figures and include the appropriate units.)
