What happens when an object is dropped? A. Its velocity at 2 seconds is 19.6 m/s. B. Its velocity at 2 seconds is 22 mph. C. Its velocity at 2 seconds is 9.8 m/s. D. Its velocity at 2 seconds is 20 km/h.

jabez177 (jabez177):

I think it's either A or B. B because it is so fast, it does not stop.

@imqwerty

jabez177 (jabez177):

But at the same time I think it's A because I don't remember my teacher telling me it in Mph, it was always miles per second or m/s.

@just_one_last_goodbye, Kevin, please help me! :(

OpenStudy (just_one_last_goodbye):

am I to late?

jabez177 (jabez177):

Not exactly, can you help me?

OpenStudy (bannana43):

what lesson is this.

OpenStudy (bannana43):

yes, what lesson is this

jabez177 (jabez177):

@AlexandervonHumboldt2 i'll give u a testimonial

OpenStudy (bannana43):

i think it is A, i am not sure.

OpenStudy (alexandervonhumboldt2):

wait, there is nothing more given?

jabez177 (jabez177):

No, sir.

OpenStudy (alexandervonhumboldt2):

oh yeah, the velicity of free faling is 9.8. 9.8*2=19.6

OpenStudy (alexandervonhumboldt2):

i meant the acceleration

jabez177 (jabez177):

So the answer is A. Thanks, Shurik! :)

OpenStudy (alexandervonhumboldt2):

oh wow i got so confused in terms

OpenStudy (bannana43):

Yes it is A

OpenStudy (whpalmer4):

dropping an object from rest, the velocity will be \[v = gt\]where \(g = 9.8\text{ m/s}^2\) if you are working in SI units or \(g = 32.2\text{ ft/s}^2\) if working in US units.
