Answer:
a) Δx ≈ 8.4 m
b) v ≈ 6.1 m/s
Explanation:
Given:
v₀ = 1.5 m/s
a = 2.1 m/s²
t = 2.2 s
a) Find: Δx
Δx = v₀ t + ½ at²
Δx = (1.5 m/s) (2.2 s) + ½ (2.1 m/s²) (2.2 s)²
Δx ≈ 8.4 m
b) Find: v
v = at + v₀
v = (2.1 m/s²) (2.2 s) + (1.5 m/s)
v ≈ 6.1 m/s

The exosphere has high temperatures and low gravity
According to Newton's law, action and reaction are equal and opposite.
<h3>What is action and reaction?</h3>
According to the Newton's third law of motion, action and reaction are equal and opposite. As such, when the arrow hits the vertical wood board, the board exerts some force on the arrow.
We can not determine the magnitude of this force numerically because the question is incomplete.
