(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The U-2 was an American spy plane capable of flying up to 21 km high at speeds over 600km/h. Determine the time required for the missile to reach its maximum altitude of the U-2.

2. Relevant equations

d=v_i t+1/2 at^2

3. The attempt at a solution

d=21000m

a=-9.81m/s^2

v_i=0

t=?

I dont know how to get time by itself and I have tried using the quadratic formula.
