find velocity and time, help needed

[andrija]

1.Assuming a constant rate of acceleration due to gravity of 32 feet per second per
second, find the initial velocity needed to launch a projectile from the surface of the
earth to a height of 900 feet.

2. Suppose that the probability distribution function for customers waiting to be
seated at a certain restaurant on a certain evening has the form f(t) = ce^-ct for
t > 0, where c = 1/10 is the reciprocal of the average waiting time in minutes. Find
the time T such that exactly 5% of customers wait longer than T minutes to be
seated. Round your answer to the nearest minute.

For problem #1

What are the equation that combine the acceleration, intial velocity, final velocity and the distance travelled?

For problem 2 - what is that ��? Please fix it and show your work.

Please share your work with us, indicating exactly where you are stuck - so that we may know where to begin to help you.
