Answer:
62.6 m/s down
Explanation:
Taking downward to be positive:
Given:
v₀ = 0 m/s
Δy = 200 m
a = 9.8 m/s²
Find: v
v² = v₀² + 2aΔy
v² = (0 m/s)² + 2 (9.8 m/s²) (200 m)
v = 62.6 m/s
The answer is B because of the earth having the same type of gravity
Answer:84.405m,
Explanation:
Given
Person walk 42 miles due to north so its position vector is
Now he deviates to east and walk 65 miles
so its new position vector
So magnitude of acceleration is
for direction
