A car is moving at 5 m/s. 2 seconds later, it is traveling at 17 m/s. How far did the car go?
Equation 1: Vf = Vo+at
Equation 2: Vf2=V0+2ad
Equation 3: Xf=X0+vot+12at2
Equation 4: Xf=X0+(vf+vo2)t

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
