If the car has a mass of 0.4 kg, the ratio of height to width of the ramp is 19/85, the initial displacement is 1.9 m, and the change in momentum is 1.27 kg*m/s, how far will it coast back up the ramp before changing directions (meters)?
Answers: 3
![\delta p = m \sqrt(2g * y/x)* [\sqrt li + \sqrt lf]](/tpl/images/0129/7823/fbdbb.png)
![1.27 = 0.4\sqrt(2*9.81 *(19/85))* [\sqrt 1.9 + \sqrt lf]](/tpl/images/0129/7823/85b06.png)
