A piece of marble is projected from Earth's surface with velocity of 19.6 2 ~m / s at 45^ . After 2 s , its velocity makes an angle with horizontal, where is

Options

  1. A45^
  2. B30^
  3. C60^
  4. D0^

Correct answer

D. 0^

Step-by-step solution

u_x=19.6 ~m / s and u_y=19.6 ~m / s . After 2 s , vertical component of velocity v_y will become zero. So, particle is at its highest point.
