Arock falls from a cliff. what is its displacement after 2 seconds, in m?

A rock falls from a cliff. 19.6 m is its displacement after 2 seconds

19.6 m

Explanation:

The rock falling from the cliff falls under the effect of gravity. And as it falls, the initial velocity is zero. To calculate the displacement of the rock which fell from the cliff, after 2 seconds, use the equation of motion, as follows,

We know that 2nd equation of motion,  

Given that t=2 sec and u=0. Putting the values into the equation, we get,

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong

probably not if net force is zero
