Diagram B .... light shines through at an angle
Answer:
39.6 m/s
Explanation:
Taking down to be positive:
Given:
v₀ = 0 m/s
a = 9.8 m/s²
Δy = 80 m
Find: v
v² = v₀² + 2aΔy
v² = (0 m/s)² + 2 (9.8 m/s²) (80 m)
v = 39.6 m/s
Using the equation P = W/t to solve your problem .
Thus the answer is all of them use the same amount of power. 20 J.
I think is altitude because tbh it don’t even mean nothing
