On the left is a drawing of what scientist Thomas Young demonstrated in the early nineteenth century when he conducted an experi
ment in which he allowed sunlight to pass through two tiny slits in an aperture (labeled "A" and "B").
Young saw a distinct interference pattern, similar to the one shown on the right, in which light waves added together at some points (making them brighter) and canceled each other out at other points (resulting in dark spots).
What would Young have seen if light did not exhibit any wave characteristics?
A. The light would have only interfered constructively.
B. The light would have only interfered destructively.
C. No light would have made it through the aperture.
D. The light would have appeared as two separate beams.

Answer:
Explanation:
F = ma and
We have F, we have m, but in order to solve for v, we need a.
30.0 = 3.00a so
a = 10.0 m/s/s. Plug that in for a in the second equation and solve for v:
so
v = 10.0(3.00) so
v = 30.0 m/s
We know, by conservation of energy :
Therefore,
Putting given values, we get :
Therefore, the spring be compressed to 6.93 cm to send the ball twice as high.
Hence, this is the required solution.
