A man who could only find a 75-kg blue rock nearby decides to drive a metal beach umbrella pole down into the soft sand of Galveston beach by dropping it straight down from a resting height of 2.3 meters. If the blue rock does not rebound off the pole just after contact (that means bouncing back and possibly hitting him in the head) then calculate the impulse the rock places on the umbrella pole. Assume the metal beach umbrella has a total mass of 175-kg
