Make hours to seconds to match meters
19.6*3600=70560 seconds
And is dropped from a height of 15.4 meters then the velocity will be
15.4m/70560s = 0.0002182539m/s
Factors of 32-
1*32
2*16
4*8
1, 2, 4, 8, 16, and 32 are factors of 32 (Their multiples are 32)
I´m pretty sure that the terms would just be 3, 4, and 5. It depends what kind of problem it is.
