A rocket accelerates at 25m/s^2 for 5s before it runs out of fuel and dies. What is the maximum height reached by the rocket?
sineoko [7]

Answer:

1109m

Explanation:

The distance h₁ traveled by the rocket during acceleration:

h_1=\frac{1}{2}at^2

The velocity v₁ at this height h₁:

v_1=at

When the rocket runs out of fuel, energy is conserved:

E=\frac{1}{2}mv_1^2+mgh_1=mgh_2

Solving for h₂:

h_2=\frac{v_1^2}{2g}+h_1=\frac{(at)^2}{2g}+\frac{1}{2}at^2
