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.

the answer is a. at the equator

this means that the temperature of both substances will be equal
