Hi,
I need help with solving this problem:
We throw an object from the hight of 12,261 meters. In the first second it is travelling with the speed of 4.904 m/s and accelerating by 9.808 m/s every second. How long will it take for the object to hit the ground?
I figured out we can use the basic formula for arithmetic sequence where a1=4.904 and d=9.808. This way we get an=9.808*n - 4.904 but I wasn't 100 % sure how to continue. I thought that Sn might be 12,261 and then used the sum formula to calculate that the time (represented by n) would be 50.002039 seconds.
Is this approach and result correct?
Thanks in advance for your help.
