You are standing on a cylindrical raft, which is floating on water. Initially the raft together with you is rotating with angular velocity =0.1 s-¹. Then you start running along the periphery in order stop the rotation of the raft. How fast and in what direction should you run? Your mass is 75 kg, the raft has mass 200 kg and its radius is 15 m.

The tires of a car make 70 revolutions as the car reduces its speed uniformly from 90.0 km/hkm/h to 65.0 km/hkm/h. The tires have a diameter of 0.88 mm. What was the angular acceleration of the tires? If the car continues to decelerate at this rate, how much more time is required for it to stop? If the car continues to decelerate at this rate, how far does it go? Find the total distance.

The earth spins on its axis once a day and orbits the sun once a year. Determine the average angular velocity of the earth as it spins on its axis and orbits the sun. In each case take the positive direction for the angular displacement to be the direction of the earths motion
Suppose a 40-kg child is on the roundabout. Treat the roundabout as a 50-kg solid cylinder with a radius of 2 m that rotates about its center. The child begins 2 m from the center of the roundabout and the roundabout has an angular velocity of 0.3 rev/s. The child then moves to 0.5 m from the center of the roundabout. What is the final angular velocity?
QUESTION 2 Which of the following is an accurate statement? O A. It is possible to add a scalar quantity to a vector. O B. Even though two vectors have unequal magnitudes, it is possible that their vector sum is zero. OC. Rotating a vector about an axis passing through the tip of the vector does not change the vector. OD. The magnitude of a vector is independent of the coordinate system used. O E. The magnitude of a vector can be zero even though one of its components is not zero.
