An object falls from a high building from rest. Ignotning air resistance, what will its velocity be after 6 seconds of falling

58.8 m/s downward.

Explanation:

Gravity adds 9.8 m/s to the speed of a falling object every second.

If it started out with zero speed, then after 6 seconds,

its speed is

                      (6) x (9.8 m/s)  =  58.8 m/s .

Its velocity is  58.8 m/s downward.

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
