Acceleration Due to Gravity Problems

V f = v i + gt y = 1/2gt 2 1. You drop a baseball from your window. When the ball leaves your hand it is traveling at 25 m/s, after 1 second what is the balls velocity? 2. While eating dinner your hand slipped and your fork fell down from your table. If it took the fork 0.5 seconds to fall, how high off the ground is the tabletop?

V f = v i + gt 1. You drop a baseball from your window. When the ball leaves your hand it is traveling at 25 m/s, after 1 second what is the balls velocity? V f = 25m/s + (-9.8m/s 2 )(1 s) V f = 25m/s + (-9.8m/s 2 ) V f = 15.2m/s

y = 1/2gt 2 2. While eating dinner your hand slipped and your fork fell down from your table. If it took the fork 0.5 seconds to fall, how high off the ground is the tabletop? y = 1/2(9.8m/s 2 )(0.5s)(0.5s) Y = m
