I rictionless surface L3 (17 points) Conservation of Energy A toy car with mass m is initially at rest next to a spring with spring constant k, that is initially compressed a distance x (not shown in the gure). After the car leaves the spring, it moves to the left a distance L along a frictionless at track. (a) What is the velocity of the car as it leaves the spring? Write your answer in terms of some or all of the given variables (m, k, x, L, and g). (4 pts) The car then moves down a ramp as shown, where there is friction. The car comes to a stop after moving a distance D down the ramp. 0.)) What is AUg? Write your answer in terms of some or all of the given variables (m, k, x, L, D, 6, and g). (3 pts) (c) What is the magnitude of the kinetic friction force experienced by the car on the incline? Write your ansWer in terms of some or all of the given variables (m, k, x, L, D, 3, and g).
