What happens if we add a lump of ice to a tumbler containing water? how does heat flow?

The ice will melt

Heat flows from the water to the ice

Explanation:

If we add a lump of ice to a tumbler containing water, the ice lump will melt in the water.

This is a simple physical change of state from solid to liquid.

At the end both the solid ice and the original liquid maintains the liquid state.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
