For a stone thrown from a tower of unknown height, the maximum range for a projection speed of 10 ~m / s is obtained for a projection angle of 30^ . The corresponding distance between the foot of the tower and the point of landing of the stone is

Options

  1. A10 m
  2. B20 m
  3. C(20 / 3 ) m
  4. D(10 / 3 ) m

Correct answer

D. (10 / 3 ) m

Step-by-step solution

= u ^2 Rg R= u ^2 ~g = 100 10 3 = 10 3
