= You are designing a small cart and ramp system with a rubber band that has a spring constant k 140 N/m. The cart has a mass of m = 0.74 kg, and it is tied to the rubber band. The frictionless ramp is at an angle of = = 14.8 with = the horizontal. After launching from the bottom of the ramp, the velocity of the cart is vo 6.28 m/s when the rubber band is at its initial length of lo 0.31 m. What is the maximum length of the rubber band before the cart comes to a temporary stop? Round your answer to 2 decimal places. Input your answer ? Your answer... m start end lo k vo m m
