45. Taking the + y direction downward and y 0 =0 ,w ehav e y = v 0 t + 1 2 gt 2 which (with v 0 = 0) yields t = p 2 y/g . (a) For this part of the motion, y =50msothat t = r 2(50) 9 . 8 =3 . 2s .

Unformatted text preview: total time is t = r 2(100) 9 . 8 = 4 . 5 s . The di±erence between this and the answer to part (a) is the time required to fall through that second 50 m distance: 4 . 5 − 3 . 2 = 1 . 3 s ....
