You took a running leap off a high diving platform. you were running at 3.1 m/s and hit the water 2.4 seconds later. how high was the platform, and how far from the edge of the platform did you hit the water? assume your initial velocity is horizontal. ignore air resistance.

The distance you free-fall from rest is  D = (1/2) (g) (T²) <== memorize this

Height of the platform = (1/2) (9.8 m/s²) (2.4 sec)²

Height = (4.9 m/s²) (5.76 s²)

Height = (4.9/5.76) meters

Height = 28.2 meters (a VERY high platform ... about 93 ft off the water !)

Without air-resistance, your horizontal speed doesn't change.  It's constant.  Traveling 3.1 m/s for 2.4 sec, you cover (3.1 m/s x 2/4 s) = 7.4 m horizontally.

hi i’m sorry to call us today so we will get back with y’all and we will have to do it haha omg was the day
