Sarah kicked a ball in the air. The function f models the height of the ball (in meters) as a function of time (in seconds) after Sarah kicked it

Answers

The function that models the height of the ball (in meters) as a function of time (in seconds) after Sarah kicked it is h(t) = vt - ¹/₂gt².

Equation of the motion of the ball

The equation of the motion of the ball is calculated from the second kinematic equation as shown below.

h(t) = vt - ¹/₂gt²

where;

h is the maximum height reached by the ball
v is the initial vertical velocity of the ball
g is acceleration due to gravity
t is time of motion of the ball

Thus, the function that models the height of the ball (in meters) as a function of time (in seconds) after Sarah kicked it is h(t) = vt - ¹/₂gt².
