The ray diagram shows a vase that is placed beyond the center of curvature of a concave mirror.
2 answers:
Answer:
The property of concave mirror says that the line which is coming beyond center of curvature will come back to focus and parallel to the focus
And the image will be between center of curvature and focus. And arrow shows the image the way it will appear.
Please look at the attachment to see the object
Therefore, option D is correct that is it will be smaller than the vase and inverted.

To solve this problem it is necessary to apply the kinematic equations of motion and Hook's law.
By Hook's law we know that force is defined as,
Where,
k = spring constant
x = Displacement change
PART A) For the case of the spring constant we can use the above equation and clear k so that
Therefore the spring constant for each one is 11876.92/2 = 5933.46N/m
PART B) In the case of speed we can obtain it through the period, which is given by
Re-arrange to find \omega,
Then through angular kinematic equations where angular velocity is given as a function of mass and spring constant we have to
Therefore the mass of the trailer is 4093.55Kg
PART C) The frequency by definition is inversely to the period therefore
Therefore the frequency of the oscillation is 0.4672 Hz
PART D) The time it takes to make the route 10 times would be 10 times the period, that is
Therefore the total time it takes for the trailer to bounce up and down 10 times is 21.4s
