An acorn falls from a tree. How fast is the acorn moving after 1.2 seconds?
A. 9.8 m/s
B. 1.2 m/s
C. 8.2 m/s
D. 11.8 m/s
Answered by admin @
Answer;
D. 11.8 m/s
Explanation;
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
≈ 11.8 m/s
