Questions
A cricket fielder can throw the cricket ball with a speed . If he throws the ball while running with speed at an angle to the horizontal, what is the effective angle to the horizontal at which the ball is projected in air as seen by a spectator?
detailed solution
Correct option is B
Consider the adjacent diagramInitial velocity in x-direction, ux=u+v0cosθInitial velocity in y-direction, uy=v0sinθwhere, angle of projection is θNow, we can writetanθ=uyux=v0sinθu+v0cosθ⇒ θ=tan-1v0sinθu+v0cosθTalk to our academic expert!
