On a circular table, A and B are moving on the circumference. Man A runs behind man B to catch him A runs with constant angular speed  ω1 with respect to table and B runs at constant tangential speed v2 with respect to ground. If it is found that the table rotates 30° in the opposite direction in every one second and the initial angular separation between A and B is 30°, then A catches B after : (Radius of table is 3 m).
  • a)
    0.5 sec, if ω1 = 4π/3 rad/s and v2 = 6.28 m/s
  • b)
    A can not catch B within 0.5 sec ω1 = π/6  rad/s and v2 = 6.28 m/s
  • c)
    0.5 sec, if  ω1 = 4π/3 rad/s and v2 = 3.14 m/s
  • d)
    0.5 sec, if  ω1 = 5π/6 rad/s and v2 = 3.14 m/s
Correct answer is option 'B,D'. Can you explain this answer?

If A runs behind B to catch him, it means that A is trying to reach the same point on the circumference of the circular table where B is currently located.

Since A runs with a constant angular speed, it means that A covers the same angle in the same amount of time regardless of their position on the circle. This implies that A moves faster when B is farther away and slower when B is closer.

If B is moving at a constant speed on the circumference, it means that B covers the same distance in the same amount of time regardless of their position on the circle.

Therefore, if A runs behind B to catch him, A needs to cover the same distance as B in the same amount of time. In order to do this, A needs to adjust their speed according to the distance between A and B. A will run faster when B is farther away and slower when B is closer.

In summary, A runs with a constant angular speed but varies their linear speed to catch up with B on the circular table.
