Answer:
14.2 m
Explanation:
Using conservation of energy:
PE at top = KE at bottom
mgh = ½ mv²
h = v² / (2g)
h = (16.7 m/s)² / (2 × 9.8 m/s²)
h = 14.2 m
Using kinematics:
Given:
v₀ = 16.7 m/s
v = 0 m/s
a = -9.8 m/s²
Find: Δy
v² = v₀² + 2aΔy
(0 m/s)² = (16.7 m/s)² + 2 (-9.8 m/s²) Δy
Δy = 14.2 m
The image is always virtual and erect. The image is highly diminished or point sized. It is always formed between F and P.
Answer:
The answer is X
Explanation:
Cause the highest points will most likely have the most potential energy
A theory of matter and energy based on the quanta concept
I think the answer is 2 km south. This is because when someone moves 4km south and moves 2km north, the final position 2km south. and if the person moves 5 km farther north,the position is now 3km north and if he moves 5km south, the final position is 2km south.
