The diagram below shows the location of three stars in space.
the light from star 2 reaches star 1 in 63 years. if star 3 is 75 light years from star 2, which of these conclusions about the stars is correct? (2 points)
star 2 is 75 miles away from star 3.
star 2 is 63 kilometers away from star 3.
star 1 is 12 light years away from star 3.
star 1 is 138 light years away from star 3.

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?
