Marilyn Howe · Answer 1

Anything that's not supported and doesn't hit anything, and

doesn't have any air resistance, gains 9.8 m/s of downward

speed every second, on account of gravity. If it happens to

be moving up, then it loses 9.8 m/s of its upward speed every

second, on account of gravity.

(64.2 m/s) - [ (9.8 m/s²) x (1.5 sec) ]

= (64.2 m/s) - [ 14.7 m/s ]

= 49.5 m/s. (upward)
