Answer:
part a: 4.25s
part b: 180.625m
Explanation:
part a:
what we know: vi=42.5m/s
t=?
vf=0
g= -10m/s^2
----------------------------------------------------------
equation: vf-vi/g=t
plug in: -42.5m/s/ - 10m/s^2 = 4.25s
-----------------------------------------------------------
part b: 42.5m/s x(times) 4.25s = 180.625m
