10 pts
A marble rolling across a shelf with a velocity of 3.04 m/s reaches the
edge of the shelf and rolls over the edge. If the marble hits the floor
1.173 meters away from the point on the floor directly beneath the edge
of the shelf, the top of the shelf is m above the floor.

Answer:

0.729 meters

Explanation:

d=(V0)t+(1/2)at^2

d=height of shelf

a=9.8 m/s^2 (acceleration due to gravity)

V0=0 m/s (initial downward velocity)

t=0.38586 seconds (1.173 meters/3.04 m/s)
