we are only going to calculate the 10m after it launched. i plugged my numbers into the bottom equation as best as i could and got -.023*10 = (-.178*9.8*1) = 1.97 now I am confused what 1.97 is
we need to find the friction of our car after we launch it. it rolls to a stop at 10 meters.

initial velocity after it laucnhed is 1.25 m/s
distance traveld 10m in 7s
we need to find the friction and efficiency of the car
We need to know the instentaneous velocity formula for a car launched down a hallway. we also need to figure out how to calculate all the friction involved in this. please help.
