Let's say that there is a helicopter flying through the sky and you have a blue laser and a red laser. You want to try and hit the helicopter with your laser. Which one will have a better chance
of going far enough to reach the helicopter and why?

The kinetics formula that applies to this problem is 
1. To find height, we use 1/2mv12−mg∗μ∗h sin θ = mgh where μ is equal to 0.20, v is 11 m/s and θ is 40 degrees. we cancel mass, h is equal to 5.47 meters.
2. The final speed is from 2(ug) * h sin θ  = vf2 
2(0.2*9.8) * sin 40 * 5.47= vf2 ; vf is equal to 3.71 m/s.
