Mmm tricky.
Constant velocity means there's no net force acting on the puck!
So if there's no friction or air drag force to slow it down, you don't need any force to keep that puck moving.
Once it's in motion, it stays in motion.
(Mmm isn't that a Law of Newton?)
:D
The force is 630 m/s hope this helps!
Answer:
245 m
Explanation:
v = at + v₀
50.0 m/s = a (9.8 s) + 0 m/s
a = 5.10 m/s²
x = x₀ + v₀ t + ½ at²
x = 0 m + (0 m/s) (9.8 s) + ½ (5.10 m/s²) (9.8 s)²
x = 245 m
Tha atmosphere has no effect on gravity.
