Question

A student pushes a baseball of m=0.13 kg down onto the top of a vertical spring that has its lower end fixed to a table, compressing the spring a distance of d=0.14 m from its original equilibrium point. The spring constant of the spring is k=520 N/m. Let the gravitational potential energy be zero at the lowest position of the baseball on the compressed spring. The ball is then released. What is its speed, v , in meters per second, just after the ball leaves the spring? v = 8.850m/s What is the maximum height, h , in meters, that the ball reaches above the equilibrium point of the spring? h = 3.860m What is the ball's velocity, in meters per second, at half of the maximum height relative to the equilibrium point of the spring? v0.5 =
