A boy shoots a rock with an initial velocity of 21 m/s straight up from his slingshot. He quickly reloads and shoots another rock in exactly the same way 3.0 seconds later. a) At what time the rocks collide from the moment the first rock was released

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.
