The Zero Gravity Research Facility at the NASA Lewis Re- search Center includes a 145-m drop tower. This is an evacuated vertical tower through which, among other possibilities, a 1-m-diameter sphere containing an experimental package can be dropped. (a) For how long is the experimental package in free fall? (b) What is its speed at the bottom of the tower? (c) At the bottom of the tower, the sphere experiences an average acceleration of 25g as its speed is reduced to zero. Through what distance does it travel in coming to rest?
