Weight
= Mass x Gravity
0.04593 Kg x 1.62 m/s2 = 0.0744066 N
How much initial velocity is required to keep a golf ball in the air for 30 seconds on the moon?
TimeUp = 15s.
Angle = 60
°Vfy=Viy+at
0 m/s2 = Visin(60)+(-1.62 m/s2)(15s)
Vi = 28.06 m/s2
...how far will it go?
Vx = Vi*cos(60)
Vx = 28.06 m/s2 * cos(60)
Vx = 14.03 m/s2
Distance = Vx * Total Time
Distance = 14.03 m/s2 * 30s
Distance = 420.9 m

...and on Earth?
TimeUp = 15s.
Angle = 60
°Vfy=Viy+at
0 m/s2 = Visin(60)+(-1.62 m/s2)(15s)
Vi = 169.4 m/s2
Vx = Vi*cos(60)
Vx = 169.4 m/s2 * cos(60)
Vx = 84.7 m/s2
Distance = Vx * Total Time
Distance = 84.7 m/s2 * 30s
Distance = 2541 m
