Answer:
a=500/50 = 10 m S2
Explanation:F =m ⋅ a a = F/m a 500/50 = 10 m/S2
hope this help.
<h3><u>Answer</u>;</h3>
<u>D. 11.8 m/s</u>
<h3><u>Explanation;</u></h3>
Using the equation;
v = u + at; such that v is the velocity attained, u is the initial velocity and a is the acceleration;
In our case, acorn falling from a tree is described as free fall aided by gravity;
Therefore, initial velocity is zero, u = 0, and the acceleration is due to gravity, thus, a = 9.8 m/s² , t = 1.2 seconds
Thus;
The equation becomes;
v = gt , since; u =0, and a = g = 9.8 m/s²
v = 9.8 × 1.2
= 11.76 m/s
<u> ≈ 11.8 m/s</u>
