An object is dropped from a height of 25 meters. at what velocity will t hit the ground? a.7.0 b.11 c.22 d.49 e.70

Given data

height (h) = 25 m ,

velocity (v) = ?

we know that,

                     v²-u² = 2as

                      initial velocity (u) = 0,

                                                a = g = 9.8 m/s ,

                  Now the equation becomes,

                                     v² = 2 × g × h

                                         = 2 × 9.8 × 25

                                     v² = 490.5

                                     v = √490.5

                                    v = 22.1 m/s

Therefore answer is C , i.e., 22 m/s (If you like this procedure, give me brainiest)

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
