Ou launch a model rocket from ground level. it moves directly upward with a constant acceleration of 76.0 m/s2 for 1.25 seconds, at which point it runs out of fuel. assuming air resistance on the rocket is negligible, what is the maximum altitude (above the ground) achieved by the rocket?

59.375 m

Explanation:

This can be studied as a UAM (Uniformly Accelerated Motion). To find the maximum altitude we can use the following formula:

We know that the rocket starts ar rest, so Vo = 0. So max altitude is calculated im the following way:

this is a good question! i'll do some research and come back when i have the answer!

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.
