A video game says it has realistic motion...like real objects on earth, where free fall acceleration is a=-10m/s my hobbit character shoots a flaming arrow -25m/s (Vs) straight down on orcs invading the castle. It hits orcs 1.5 seconds later at 50m/s finale speed (Vf). Find the games freefall a for this arrow

The answer to your question is a = 50 N/kg

Explanation:

Data

t = 1.5 s

vo = -25 m/s

vf = 50 m/s

a = x

Formula

 vf = vo + at

solve for a

 at = vf - vo

 a = (vf - vo) / t

Substitution

 a = (50 - - 25) / 1.5    The problem is giving a negative vo so it will be positive

 a = (50 + 25) / 1.5

Simplification

 a = 75/1.5

Result

 The game free fall a = 50 N/kg

think its the third option

the closer the planet is to the sun, the larger the gravity
