The height of a stuntperson jumping off a building that is 20 m high is modeled by the equation h = 20 – 5t2, where t is the time in seconds. a high-speed camera is ready to film the person between 15 m and 10 m above the ground. for which interval of time should the camera film the person

Step-by-step explanation:

       The height of the stuntperson jumping off a is modelled as . Here is the time in seconds.

       We have to record the person when he is between the heights from the ground.

       When ,

       When ,

       The stuntperson is at height at , and is at height at .

∴ The camera should film the person for the time interval .
