Denoting by r the radius of the paper roll at any given time and by b the thickness of the paper, derive an expression for the angular acceleration of the paper roll.In a pulley system shown, find the tension on the cable and the acceleration of pulley B and the load 5kg. Acceleration of load (al-m/s²) = TENSION (N) = Acceleration of pulley (ag-m/s²) r26. From a point A, a body travels for 2 s at a constant velocity of 12 m/s due north. It then travels for 5 s due east whilst its velocity decreases uniformly from 12 m/s to 6 m/s. What is the resultant displacement from A? Also, determine the average velocity, in magnitude and direction, of the body for it to return along straight path to point A in 3 s.

When it is in contact with the floor, the lower side of the ball is temporarily flattened. Suppose the maximum depth of the dent is 1 cm. (Assume the positive direction is upward.)1. Determine the acceleration of the ball (in m/s2) while it is in contact with the floor and compressing. (Indicate the direction with the sign of your answer.) 2. Determine the velocity of the ball (in m/s) as it leaves the floor on the rebound. (Indicate the direction with the sign of your answer.) 3. What If? If instead of dropping the ball, the coach throws it down (from some unknown height) with such a speed that it bounces back up to a height three times its original height, determine the new acceleration of the ball (in m/s2) while in contact with the floor and expanding. (Indicate the direction with the sign of your answer.)
