If a fireworks rocket has an initial upward speed of 58 m/s when launched, for how long will it coast before reaching its peak?(adsbygoogle = window.adsbygoogle || []).push({});

So could I use the equation t=v0z/g?

When I use this I get the peak to be 5.9s. Is v0z = 58 m/s or would that be 0? Am I approaching this correctly?
