Question

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.

Answer 1

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
