Questions
A light spring of length l and spring constant K is placed vertically on the table. A small ball of mass m is released on it. Height from the surface of the table at which the ball will have maximum velocity
detailed solution
Correct option is D
Acceleration a = mg - k∆xVelocity will be maximum when a = 0∴Δx=mgkSo height h = l−mgKTalk to our academic expert!
