Question:

A rocket ship in space is at rest relative to a rock floating in deep space. The rocket ship accelerates away from the rock at 3 m/s2, while it accelerates it
goes through a displacement of 108 m directly away from the rock. For what
amount of time did it accelerate? Hint: If a variable has the numerical value
zero, then you can substitute the value zero in for that variable before doing
the algebra to make the algebra much simpler.

So the equation used in this problem is ΔX=V0*T+1/2AT^2 the X is the distance, v0 is initial velocity, T is time, and a is acceleration. So when we plug these values it we get: 108= 0•T+1/2•3•T^2,the 0•t disappears, and the 1/2•3 gets us 1.5, so we have 108=1.5T^2, then we divide 108 by 1.5 which gets us 72=t^2, and we then take the square root and get 8.49=T so the answer is 8.49 seconds.
