# Thread: Integration and initial velocity

1. ## Integration and initial velocity

With what initial velocity must an object be thrown upward (from the ground to reach a maximum height of 550feet?

Use a(t)= -32fet/sec/sec as the acceleration due to gravity. (neglect air resistance)

I feel like the problem doesn't give you enough information, becuase im not sure how to apply integration to the situation.

Are you sure that it isn't:

$\displaystyle a(t) = -32t$ ?

Because $\displaystyle a(t) = -32$ wouldn't make any sense to be given as a part of this problem. If the acceleration was a constant, they wouldn't give it as a function of time.
