When given mass=0.025kg, Velocity Initial=18m/s, time=5.0 x 10^-4s, and a Velocity Final=10m/s, how do I find the force?

A golf ball is going horizontally at 18m/s and crashes into a window, and then keep going 10 m/s, how do I find the force?[o)]

You can't find the force without more info. What you can find is the impulse imparted to the ball = mΔv. The impulse equals the force x time (duration) of the interaction. So, if you knew the time that the window interacted with the ball, you could figure out an average force.

I'm sure some clever engineer can come up with some reasonable assumptions about the strength of materials, but that's probably not what you are looking for.
