Aflower pot falling 45 meters hits the ground with a speed of . about 60 m/s. b. about 120 m/s. c. more than 120 m/s. d. about 30 m/s.

d. about 30 m/s.

Explanation:

we use the equation for final speed in free fall:

where is the final speed, the initial speed, in this case , is the acceleration of gravity and is the height:

so replacing all known values:

we use the equation for final speed in free fall:

so the answer is:  d. about 30 m/s.

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
