Asked Nov 4, 2019

A student pushes a baseball of *m* = 0.18 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 meters. The spring constant of the spring is *k* = 680 N/m. Let the gravitational potential energy be zero at the position of the baseball in the compressed spring.

*m* = 0.18 kg*k* = 680 N/m*d* = 0.14 m

**a.) **The ball is then released. What is its speed, *v*, in meters per second, just after the ball leaves the spring?

**b.)** What is the maximum height, *h*, in meters, that the ball reaches above the equilibrium point?

**c.)** What is the ball’s velocity, in meters per second, at half of the maximum height relative to the equilibrium point?

Step 1

a)

The required speed from conservation of energy is,

Step 2

b)

The required maximum...
