Consider a system of two objects and earth. Object x and object y are held together by a light string as shown in the figure. My is larger than mx. The two-object system is released from rest in the orientation shown in the figure at a height h above earth’s surface. The change in the kinetic energy of the system from when it is released to the instant it hits the ground is most nearly.

The change in the kinetic energy of the system from when it is released to the instant it hits the ground is most nearly; (My + Mx)gH

We are told that the two objects X and Y are held together by a light string.

Their masses are;

Mass of Object X = Mx

Mass of objetc Y = My

Since the two objects are released from rest, it means we need to find potential energy and the formula for potential energy is;

P.E = mgh

Now, since both objects are released from rest and since My is larger than Mx, it means that potential energy is now;

ΔP.E = (My + Mx)gH

Now, according to conservation of energy,

Change in kinetic energy = Change in potential energy.

Thus;

Change in kinetic energy = (My + Mx)gH
