A batsman hits a ball with a velocity 'v', making an angle of 60^ with the vertical. After some time direction of velocity is making an angle of 60^ with the horizontal. The speed of the ball at this instant is [ (60^ ) = 1 2 , (30^ ) = 3 2 ]

Options

  1. A3 2 v
  2. B3 v
  3. Cv 2
  4. DV

Correct answer

B. 3 v

Step-by-step solution

The initial angle of the velocity with the vertical is 60^ . Therefore, the initial angle with the horizontal is 90^ - 60^ = 30^ . The horizontal component of the initial velocity is u_x = v (30^ ) . Let the speed of the ball be v' when its direction of motion makes an angle of 60^ with the horizontal. The horizontal component of velocity at this instant is v'_x = v' (60^ ) . In projectile motion, the horizontal component of velocity remains constant throughout the flight. Equating the horizontal components of velo
