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

A model rocket leaves the ground , heading straight up at 49 m/s

a) what is its maximum altitude?

b) what are its speed and altitude at 1,4 & 7 seconds

2. Relevant equations

v=v0 + at

x= x0 + 1/2 (v0 + v) t

x= x0 + v0t + 1/2 at^2

v^2=v0^2 +2a (x-x0)

3. The attempt at a solution

Am able to work out maximum altitude no problem , for some reason cant get my head around b) ?
