let s(t)= -16t^2 + 50 represent the distance in ft. from the ground of an object t seconds after initial velocity of the object? initial means t=0

1. what is the initial velocity of the object?

2. what is the velocity of the object 1 sec after it was released?

3. when does the object hit the ground?

4. what is the object's velocity as it his the ground?
