Find the maximum compression in a spring of spring constant 800 N/m, if it is hit by a ball of 0.5 kg released from the height of 10 m. The ball initially followed a curved path and then move horizontally on a frictionless surface to meet the target.

From the conservation of mechanical energy, we have

Now, let the maximum compression of the spring be "x". Then, according to "work - kinetic energy" theorem
kf  − ki = W
Here, speed at maximum compression is zero. Thus, Kf is zero.
