Question

What is the ratio of the time it takes to throw the ball vertically at a speed of ?_〖0〗 from the ground, to throw it at an angle of 30° to the ground, and how long it takes for the ball to reach the ground again?

Answer 1

In this question we have to find the ratio of time taken in vertical flight and projectile motion at 30 degree angle

When a ball is thrown vertically up with initial speed of Vo from the ground then time taken by object to return back to the ground is as follows final speed veo V=utat o=o-gt max. beight havo ag Now t = vo j c whon ball moves up) 1 when ball moves down uro final speed an s=ut that -h=o- gth =) - Vo? 2 - 381,3 Jg Vo t, - = Volg ttt'a teral time = cols Vo g avo 9 or T20,2038 Vo see when ball is thrown at 30° angle from ground then time taken by ball to reach max. max, height= Vosingo ܩܘ VO. total time tekens Ho go up and come back= 2vosingo g T-o.102 Vosee Vertical flight 210/3 Time natio = 2 Inclined flight sino avosin30 g
