After studying the graph and locating the vertex of the parabola. The maximum height of the rock is 64 feet. It is reached after a second.
How to obtain information from free fall equation by graphical approach
Free fall is an uniformly accelerated motion due to gravitation, whose expression is of the form:
h = -(1/2) · g · t² + v' · t + h' (1)
Where:
- g - Gravitational constant, in feet per square second.
- v' - Initial speed, in feet per second.
- h' - Initial height, in feet
- t - Time, in seconds
Graphically speaking, the model represents a parabola. The maximum height is the vertical component of the vertex of the curve and its time is the horizontal component.
Hence, the maximum height of the rock is 64 feet. It is reached after a second.
