A cart moves to the right along a frictionless track. What is the minimum speed of the cart at point 1 such that it can reach point 2? Use g = 10 m/s2 20.0 m 15.0 m 10.0 m 0 14.1 m/s depends on the mass of the cart 17.3 m/s O 10.0 m/s 20.0 m/s Question 5 1 pts A ball rolls without friction along a track of changing elevation (vertical coordinate). The total energy (red line) and potential energy U (blue curve) versus horizontal distance x is shown in the figure below. The unit of energy is J (1) per grid line) and the unit of distance is m (0.5 m per grid line).
