1. [1pt]
Consider a Gaussian wave pulse with amplitude 1 cm travelling on a
4 m long string with two free ends, as shown. If the wave travels
at 1 m/s, then what is the displacement y at x = 0 m and t = 6 s?
Make sure you can explain your reasoning in terms of the physics of
wave reflections and superposition.

Two particles A and B of mass m kg and 3 kg respectively are connected to a light string. The particle A is held stationary on smooth plane and the system is released to move. Immediately after the release, B moves downward with an acceleration 0.4 g. Find the normal reaction of the surface on A just after the release of the system.
