help with projectile motion qn (1 Viewer)

[bos1234]

How do i find the range of the projectile and the time of flight if i have the distance the ball travells and the agnle at which it is set?

 

[chousta]

There are 2 ways generally to attain the range.

there is a simple formula

1. Range=(u^2 sin2@)/g
2. or the more formal method:
   (Delta) y=0
   then you find the time of the flight
   sub that into the range formula
   R=(Delta)X (y)=Ux.t

hope that helps if u want more info pm me, its hard to explain when i dont know how to do the subscripts and stuff.

ps. for your case you would use formula no. 2 and work your way backwards
