My question is: what equation will model a situation where a pebble is dropped from 10 meters directly above someone's head when the height of the pebble after "t" seconds is given by h=-4.9t^2+vt+h? Here is a picture of my assignment...

A small pebble is dropped from 10 meters directly above your head. The height of the pebble after t
seconds is given by:
h= -4.9t2 + Vot+ ho,
where t is measured in seconds, h in meters, Vo is the initial velocity and ho is the initial height.
Replace -4.9 with -16 when h is measured in feet.
Write an
equation that models this situation:
Graph using an appropriate domain.
