A rocket is launched at an angle of 53.0° above the horizontal with an initial speed of 99 m/s. The rocket moves for 3.00 s along its initial line of motion with an acceleration of 32.0 m/s2. At this time, its engines fail and the rocket proceeds to move as a projectile.
(a) Find the maximum altitude reached by the rocket.
(b) Find its total time of flight
(c) Find its horizontal range

I tried plugging in a few equations but i cant even seem to find A.

1. The equation of motion of a particle, where s is in meters and t is in seconds, is given below.
s = 7 t ^3 + 3 t ^2 + 8 t + 3
(a) Find the velocity and acceleration as functions of t.
b) Find the acceleration after 3 s.

2. Find the points on the curve given below, where the tangent is horizontal.
y = 7 x ^3 + 2 x ^2 - 4 x + 7
P1 = ( , ) (smaller x-value)
P2 = ( , ) (larger x-value)

3. Find an equation of the line that is both normal to the given parabola and also parallel to the given line.
yp = 6 x ^2 - 4 x + 5
8 x - 5 y = 2

Really, thank you to eternity and back!

...the inability to feasibly achieve a greater speed, or the inability to protect the vessel from micro-impacts? I'd like to hear ideas on what kind of shielding would be needed at speeds of 300 to 3000 Km/sec., considering what would be the effect of hitting a micrometeoroid at that speed. Or even the effect of interstellar gas, as sparse as it may be. Also, would there be any practical way of detecting a dangerous object which would destroy any reasonable sized shield, in time to alter the ship's course the tiny amount needed to avoid it? Say, for example, the size of a baseball.

mass is equal to energy

if you add energy to an object, then are you also adding matter? where does this matter come from and go?

Now i do believe in extraterrestrial life. Reason being that there is no possible way that we are the only social beings in the universe. If there is photographic proof the other galaxies and all that other good stuff, then why would this Earth be the only place life is? It just would make sense at all. Now if you think otherwise, what is your reason for the Earth being the only planet in the universe with life?
