Answer:
8 m/s² south
Explanation:
Given:
v₀ = 40 m/s
v = 0 m/s
Δx = 100 m
Find: a
v² = v₀² + 2a (x − x₀)
0² = 40² + 2a (100)
a = -8
The acceleration is 8 m/s² south.
All forces on the bullets cancel so that the net force on a bullet is zero, which means the bullet has zero acceleration and is in a state known as constant velocity. The bullet is moving at a constant value of velocity. Acceleration is the rate of velocity so having zero acceleration would mean that there is no change in velocity per unit of time.<span />
I believe it is D I’m sorry if it’s wrong
Answer:
1000 m upwards
Explanation:
Displacement Formula: Average Velocity = Displacement/Total Time
Simply plug in our known variables and solve:
100 m/s = x m/10 seconds
100 m/s(10 s) = x m
m = 1000
