# Two dimensional motion problem.

## 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 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.

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.
$$V_0x$$= 45m/s cos(45)
$$V_0y$$=45m/s sin(45)

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

am I wrong?

Good work, you're right.
