A toy car of mass m is pushed against a spring, compressing it a distance d from its natural rest length. The spring exerts a force F(x) = −(kx + ßx5)ix, where x is the displacement from its equilibrium position at the origin. The car is then released from rest and slides on a table with coefficient of friction µ. (i) What is the car's speed when it reaches the origin? (ii) If the car detaches from the spring when it reaches the origin, derive an equation that could be solved to find the location of the car when it comes to rest (do not solve).

Problem 2: Suppose a car approaches a hill and has an initial speed of 108 km/h at the bottom of the hill. The driver takes her foot off of the gas pedal and allows the car to coast up the hill. a) If the car has the initial speed stated at a height of h = 0, how high, in meters, can the car coast up a hill if work done by friction is negligible? b) If, in actuality, a 770-kg car with an initial speed of 108 km/h is observed to coast up a hill and stops at a height 20.5m above its starting point, how much thermal energy was generated by friction in J?
