A stunt double in a movie jumps from a window 50 feet above the ground and lands on an air cushion that is 8 feet high. Write a equation giving the stunt double's height h (in feet) above the ground after t seconds. How long does it take for the stunt double to hit the air cushion?

I have a somewhat idea how to do this, I just don't know how to write it out with variables. Thanks for anyone who can help.

why is it that the term equal force is used if for example a cup is places on a table

the upward force on the table is said to be equal with the gravitational force of the cup.

now if you put a 1kg and a 10kg cup on a table how can the forces be the same to keep the both cups still... if the table is pushing up with the equal force on the 10kg cup, why doesnt the 1kg cup go flying into the air?
