Please see attached...solve using energy equations, ie, potential, kinetic
Calculate the maximum velocity of slider B if the system is released from rest with X = Y (the red line is a frictionless, mass less linkage of length .9 m )
Motion is in the vertical plane. Friction is negligible and the masses of A and B are equal
It shows how to calculate the maximum velocity of slider when the system is released from rest. The solution is detailed and was rated '5/5' by the student who originally posted the questions.
