1) What is the acceleration of a rock at the top of its trajectory when thrown straight upward?

Explain whether or not the answer is zero by using the equation a = F/m as a guide to your thinking.

2)A rocket fired from its launching pad not only picks up speed, but its acceleration also increases significantly as firing continues. Why is this so? (Hint: About 90% of the mass of a newly launched rocket is fuel.)

The human when reached the moon and posted the flag....It was a real or not?

I think it's fictional (not real) because they did it all in a movie set, filming on LIVE, and it was only for cash (millions of people watching the same channel...).
