A wave peak moving to the right meets a wave valley of the same amplitude moving to the left. What happens when the waves meet? A)They add up to make a larger wave for a brief second then they continue moving as before.
B)They cancel each other out and both stop moving afterward.
C)They cancel each other out for a brief moment then they continue moving as before.
D) Nothing happens to them. They travel through each other without any interactions.

Afaulty model rocket moves in the xy-plane (the positive y direction is vertically upward). the rocket's acceleration has components ax(t) = ? t2 and ay(t) = ? ? ? t, where ? = 2.50 m/s4 , ? = 9.00 m/s2 , and ? = 1.40 m/s3 . at t = 0 the rocket is at the origin and has velocity ~v0 = v0x ? i + v0y ? j with v0x = 1.00 m/s and v0y = 7.00 m/s. (a) calculate the velocity and position vectors as functions of time. (b) what is the maximum height reached by the rocket? (c) sketch the path of the rocket. (d) what is the horizontal displacement of the rocket when it returns to y = 0?
