## Homework Statement

A car is moving at 25m/s. A passenger, 1.5 m from the ground, can throw a ball at a max speed of 15 m/s and throws the ball out the window as he passes a bystander on the sidewalk. How fast is the ball moving when it leaves the passenger's hand and how far does the ball move relative to the bystander?

## Homework Equations

For X component:

distance = velocity * time

For Y component:

x(f) = x(i) +v(i) + .5at

^{2}

## The Attempt at a Solution

I believe that, relative to the bystander, the ball is moving at 40m/s. You can figure out the amount of time it takes the ball to reach the ground by solving for t for the Y component equation.

x(i) and v(i) = 0

a = g = 9.8m/s

^{2}

x(f) = 1.5m

solve, t = 0.55s

Now you just solve for the x component:

v = 40m/s

t = 0.55s

X = 22m

Is this correct? Thanks for the help.
