Question

A field researcher uses the slow-motion feature on her phones camera to shoot a video of an eel spinning at its maximum rate. The camera records at 120 frames per second. Through what angle does the eel rotate from one frame to the next?

Answer 1

`\alpha=(1/120)*14*360=42`degrees

Step-by-step explanation:

Eels have been recorded to spin at up to 14 revolutions per second when feeding in this way

So the angle the eel rotate is going to be

Camera record 120 frames per second

time taken for 1 frame record

`t_t= 1/120 seconds`

eel rotates

`\alpha_1=14rev *360`degrees in 1 second

so:

eel rotetas
`\alpha=(1/120)*14*360=42`degrees
