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. 33% Part (a) If the spring stretches x =0.245 m from equilibrium while supporting an 7.3-kg child, what is its spring constant, in newtons per meter? k = Grade Summary Deductions Potential 05 100% A33% Part (b) What is the time, in seconds, for one complete bounce of this child about the point x? A 33% Part (e) What is the child's maximum velocity, in meters per second, if the amplitude of her bounce, relative to x, is 0.215 m?
