Homework Statement


A baseball was hit at 45m/s at an angle of 45 degrees above the horizontal.
How long did it remain in the air? How far did it travel horizontally?

Hi everyone, I am i stuck :cry: on this problem any hints (formulas) to help me solve this problem would be appreciated. Thanks in advance

Today seems to be the projectile motion day. :smile:

Anyway, which are the equations for projectile motion? Start with finding the equations for the x and y displacement of the baseball.

So I need to find the time and range of the projectile.
[tex]V_0x[/tex]= 45m/s cos(45)
[tex]V_0y[/tex]=45m/s sin(45)

and Range is: [tex]R = 2{V_0x}{V_oy}/{g}[/tex]
Time is: [tex]t = {2V_0y}/{g}[/tex]

:confused: am I wrong?
