In an isolated system, a red ball of mass m moves to the right with speed v. It strikes a green ball, of mass 2m, which was initially stationary. After the collision, the red ball remains stationary. How does
the green ball move?

A. To the left, with speed v/2

B. To the right with speed 2v

C. To the right, with speed v/2

D. To the left with speed 2v

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
