Questions
A vertical spring with force constant 'k' is fixed on a table. A ball of mass 'm' at a height 'h' above the free upper end of the spring falls vertically on the spring so that the spring is compressed by a distance 'd'. The net work done in the process is
detailed solution
Correct option is B
Total displacement = (h+d)Work done by gravity = mg(h+d)Work done by the spring on the ball =12kd2Therefore Total work done =mgh+d=12kd2Talk to our academic expert!
