Answer:
f = 0.0833 Hz
Explanation:
Frequency is defined as the no. of cycles per unit time. The frequency of water waves can be given by the following formula:
here,
No. of Waves = No. of times seagull moves up and down = 5
Time = 1 minute = 60 sec
Therefore, using these values in the formula, we get:
<u>f = 0.0833 Hz</u>

Explanation:
We need to apply the accelerated motion formulas.
The acceleration is given by:
we need to calculate the time the cheetah takes to stop when it starts to decelerate:
We need to calculate the displacement for all of the stages:
stage 1:
stage 2:
stage 3:
The total displacement is given by:
the final velocity of the cheetah is zero because the cheetah decelerates until stop.
