Question

A cat jumps from a ledge to catch a hummingbird that is hovering above the ground. His jump is filmed and, using frames from the film, his height (in centimeters) is calculated to be the values shown in the table at the corresponding times measured from the start of his jump.

How high is the ledge from which he jumped? centimeters.

Assuming he barely manages to catch the hummingbird at the top of his trajectory, how high was the hummingbird hovering? centimeters.
