ok what I did was
0 = -9.8 t + 47.04
where 47 is the initial velocity and 0 is the velocity i got a time of 4.8 sec. and then when added to the 2.4 it would give me 7.2 seconds, but I heard this answers was wrong. Do you know what the problem is?
I am having trouble with this one. for all the formulas I tried I need the velocity, which they don't tell us in the problem. Any help would be appreciated .
