Answer:
using the finest square equals V initial squared. Yes, do G age For a for initial speak with zero height comes out to be refinanced. Square over to G. It was 73.5 meter for a second with the native science where of that divided by two times 9.8 meters per second square. And that comes out to be 275. Made it now a age is given by Let's just go with the V. The final is given by V initial. The last two G h reinitiate equals zero. We finally was re initial Tow us g times, time and we are using the positive sign over here. So we're using positive sign for VF as well. So from here we see that the time it was we finally over G. It was 73.5 meter for a second, divided by 9.8 meter per second squared. So that comes out to be seven, going five second
