To find the location and size of the image formed by a converging lens, you must draw two rays: one ray is from the upper tip of the object (the pen in your figure) that is in front of the mirror, parallel to the horizontal axis until the lens (Ray 1 in your figure) which then bends through the focal point (F in your figure). That is the ray that you must complete in your figure.

The attached figure shows this ray in blue.

The other ray would be from the upper tip of the pen straight through the center of the lens (this is not included in the figure, by instructions of the question).

A toy uses a spring to shoot an arrow with a suction cup on the end. The toy shoots a 34.2 g arrow and gives it a speed of 5.50

Jet001 [13]

Explanation:

When spring is used to shoot an arrow, the Elastic Potential Energy is converted into Kinetic Energy.

The efficiency of Spring Toy = 69%

According to Conservation of Energy :

P. E. = K. E.

NOW,

69% of P. E. = m * v^2 / 2

$P.E. = \frac{0.0342 \times 5.5 \times 5.5}{2 \times 0.69} = 0.75J$
