A pistol that fires a signal flare gives the flare an initial speed of 120 m/s. If the flare is fired at an angle of 55° above the horizontal, how far away will it land? a. If the flare is fired on the moon, where g = 1.6 m/s2, how far away will it land?​

See answers below

Explanation:

vf = vi + gt

0 = (120sin55°) + (-9.8)t

t = 12.2 s

12.2 x 2 = 24.4 s

x = (vi)t + (1/2)at²

x = (120cos55°)(24.4) + 0

x = 64.79 m

a.

vf = vi + gt

0 = (120sin55°) + (-1.6)t

t = 74.98 s

74.98 x 2 = 149.96 s

x = (vi)t + (1/2)at²

x = (120cos55°)(149.96) + 0

x = 398.18 m

it doesn't. it was imagined up in the middle ages.
