    Calculating Time of Flight for Ball Thrown at 45° with Initial Speed 31 m/s

    Ok I'm having a problem finding the speed at impact. I know it's the magnitude of Vx and Vy. I have Vx as Vi cos 45 = 21.92 I'm having trouble finding Vy.

    Genius.. I'm soaking it all in. :) Now to attack the rest of the ball throw problem.

    Calculating Time of Flight for Ball Thrown at 45° with Initial Speed 31 m/s

    Our posts crossed. I asked what steps you took to get 4.9s. I deleted it thinking that you were going to explain the steps.

    Calculating Time of Flight for Ball Thrown at 45° with Initial Speed 31 m/s

    Sorry dextercioby.. Ok so Y initial = 10m and Y final = 0m Yf = Yo + VoT - (1/2)GT^2 0m = 10m + (31 m/s sin 45)T - (1/2)(9.8 m/s^2)T^2 T = 6.5s Tycho is not taking my answer.

    Calculating Time of Flight for Ball Thrown at 45° with Initial Speed 31 m/s

    Well I'm confused with Y (initial) and Y (final). These are the hints that came with the problem: We know y initial and y final are both zero since both are on the ground

    Calculating Time of Flight for Ball Thrown at 45° with Initial Speed 31 m/s

    A ball is thrown with an initial speed of 31 m/s at an angle of 45°.The ball is thrown from a height of 10 m and lands on the ground. (a) Find the time of flight. http://img153.echo.cx/img153/5338/showme2mp.gif I used the following formula: Yf = Yo + VoT - (1/2)GT^2 0 = 0 + (31...
