I was given this question however could not complete it due laking the knowledge for the equations and having a us less teacher I was hoping someone could help with what equations and im not asking anyone to do my work for me just point me in the right direction

A rocket of mass 2 kg is fired vertically upwards with an initial velocity of 500 m/s. Neglecting the air resistance.

Calculate:

(i)it’s initial kinetic energy
(ii)its velocity at a height of 1 km
(iii)the maximum height reached .
 
1. KE=.5mv^2 where m = mass and v = velocity
2. V(final)^2 = V(initial)^2 + 2a(change in distance)
3. Same equation except V(final) = 0

The acceleration is going to be -9.8m/s or -10
