I think I solved the problem but tell me if I made any errors
Homework Statement
A tray of mass m, when suspended from a spring attached to the ceiling, stretches the spring by a distance Δx. A glob of peanut butter with mass M is dropped from a height h onto the tray, which is at rest...
I tried using momentum conservation and energy conservation.
momentum: (m1 + m2 + M)(Vi) = (m1 + m2)(Vf + u) + (M)(Vf)
(u is the velocity of the people respect to the sleigh
Vi = initial velocity of sleigh and people combined, Vf = final velocity of the sleigh)
energy: 1/2(m1 + m2 +...
Homework Statement
Two people of different masses are riding in a sleigh on frictionless ice.
One has mass m1 and the other has mass m2.
When they jump out of the sleigh each has speed u respect to the sleigh.
(I). What is the final velocity of the sleigh if they jump simultaneoulsy in...
