A cricket ball is thrown by a player at a speed of 20 ~m / s in a direction 30^ above the horizontal. The maximum height attained by the ball during its motion is (g=10 ~m / s ^2 ) :

Options

  1. A5 ~m
  2. B10 ~m
  3. C20 ~m
  4. D25 ~m

Correct answer

A. 5 ~m

Step-by-step solution

Given : ( u =20 ~m / s =30^ , g =10 ~m / s ^2 ) We get ( = 30^ = 1 2 ) Maximum height reached ( H = u ^2 ^2 2 ~g = 20 20 ( 1 2 )^2 20 =5 ~m )
