OK, so I've had a go. Can someone please check my answer and see if it's correct? (Sorry for the crappy formatting, I'm not sure how to do sub\superscripts)
initial velocity = 0;
acceleration = 20m/s^2;
displacement = 1379.8;
d = vi * t + 0.5 * a * t^2
1379.8 = 0m/s * t + 0.5 * 20m/s^2 * t^2...
Hi, I'm trying to solve something that I'm very sure is simple, I just can't seem to find the right equation.
A rocket is travelling straight up, with an acceleration of 20m/s^2. I need to know how long it takes to reach a height of 1379.8m (this is the second part of a question).
