Q. A uniform disk with a mass of 150 kg and radius of 2 m rotates with an angular speed of 1100 rev/min. A tangential force is applied at a radial distance of 0.65 m. The wheel is brought to rest in 2.5 min. What torque does the force produce?
Q. There are 2 inclines A & B. Identical carts are placed on the top of each incline and release them from rest. Both inclines have the similar height and are friction less, but angles of the two incline are not the similar. Would carts acceleration on A be greater than, less than or equal to its acceleration on B?
