A 3kg horizontal disk of radius 0.2m rotates about its center with an angular velocity of 50rad/s. The edge of the horizontal disk is placed in contact with a wall, and the disk comes to rest after 10s. Which of the following situations associated with linear impulse is analogous to the angular impulse that is described?a. A 3kg block is initially at rest. An applied force of 3N is applied to the block, but the block does not move.b. A 3kg block is initially at rest. A net force of 3N is applied to the block until it has a speed of 10m/s.c. A 3kg block is initially traveling at 10m/s. An applied force of 3N is applied to the block in the direction of its velocity vector for 10s.d. A 3kg block is initially traveling at 10m/s. The block encounters a 3N frictional force until the block eventually stops.
