Question 789430: If the arresting device on an aircraft carrier stops a plane in 150 m with an acceleration of 15 m/s2, find the time the plane takes to stop.
The answer is t= 4.5s.
How would I isolate t, substitute, and solve for this equation?

-------------
s = at^2/2
150 = 15t^2/2
t^2 = 20
t+=+sqrt%2820%29 seconds
t =~ 4.5 seconds
