1. Godzilla’s mortal enemy Biolante accelerates from a speed of 71 meters per second to a speed of 420 meters per second at a rate of 28 meters per second
squared. How far does Biolante travel during its acceleration?
This is the question
the equation is d=vit+1/2*at^2
but i dont know what the time is
i substitued d=71(t)+1/2*784(t)^2
