Answer:
v = 12.3 m / s
Explanation:
This is an exercise in kinetics in one dimension
v² = v₀² + 2 a x
In this exercise they tell us that the initial velocity is (v₀ = 13 m / s), the acceleration is a = -0.95 m / s2 and the distance x = 9.2 m
we substitute
v = √ (13 2 - 2 0.95 9.2)
v = 12.3 m / s
note that as the acceleration is negative the vehicle is stopping
In the image below, the focus lines are shown. The step can be done to bring the apple into focus is make the lens rounder. The correct option is A.
<h3>What is lens?</h3>
The lens is in spherical shape may be diverging or converging.
As light enters the eye, it is focused on the retina. Changing the pupil diameter, regulates the amount of light entering the eye. Changing lens shape will focus the light.
The changes in lens shape needed to maintain focus as the object distance changes.
Thus, the correct option is A.
