2. A rifle is fired horizontally and travels 980 m. The rifle barrel is 6.1 m from the ground. What speed must the bullet have been travelling at?

here i got a time of 201.24.. i then added the 980m to the 6.1m and put it in the x=vt equation to get a velocity of 69.49

I can tell your time is way off.

the bullet drops 6.1m
6.1=1/2 g t^2

t= sqrt(12.2/9.8)
Now, that is the time of flight.
980=vt solve for v.
