Answer:
1.5 m/s/s
Explanation:
This problem can be solved using equation of motion given below
where v is the final velocity
u is the initial velocity
t is the time
given
final velocity = 9 m/s
initial velocity = 0 m/s
t = 6 seconds
lets substitute these value in v = u + at
9 = 0 + a*6
=> 9 = 6a
=> a = 9/6 = 3/2 = 1.5
Thus, acceleration is 1.5 m/s/s
The correct answer is C. I leave an attached image to have a clearer idea of the light process that uses the Light when entering the eye. When you have farsightedness, the image is formed behind the eye so the defective effect is generated.
What is sought with the lenses is to correct this condition and put the image back at the point of the retina.
