A baseball was hit with a speed of 30m/s at an angle of 45 degrees. It lands on the flat roof of a 13.0 m tall nearby building.

If the ball was hit when it was 1.0 m above the ground, what horizontal distance does it travel before it lands on the building?

Step 1

The velocity along the x and y axis are

Step 2

The kinematic equation for the displacement in the y direction is

Step 3

Substitute the given values ...
