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. 2 I -12 1.3 .1 .2 3 Given that your head is 2 meters above the ground. How long will it take the pebble to hit your head to the nearest four decimal places? Label this point P on the graph. Find the average speed of the pebble between the following time intervals. slope of line Pg Time Interval 0 to 1.2778 seconds 0.5 to 1.2778 seconds 1 to 1.2778 seconds 1.2 to 1.2778 seconds 1.25 to 1.2778 seconds 1.29 to 1.2778 seconds Approximately how fast is the pebble traveling when it hits your head?
