The device pictured in the figure entertains infants while keeping them from wandering. The child bounces in a harness, with a spring constant k, and is suspended off of the ground. a) If the spring stretches x1 = 0.265 m from equilibrium while supporting an 8.05-kg child, what is its spring constant, in newtons per meter? b) What is the time, in seconds, for one complete bounce of this child about the point x1? c) What is the child’s maximum velocity, in meters per second, if the amplitude of her bounce, relative to x1, is 0.185 m?

Questions 2-5 reference the picture of mass attached to a spring shown. The left most picture gives the spring in its relaxed (equilibrium) position. The mass is lifted to point "B" and let go such that it oscillates up and down as shown in the right most position. Positions B and C are its highest and lowest points while bouncing. Point A is where the mass is traveling the fastest. Neglect air drag. 100 g BA A 100 g 100 g C At what point will the system have the largest total energy? O A В C All points will have the same amount of total energy.
