Answer:
A) 15.0 years
Explanation:
Due to the distance to the star system is in light-year units, we can compute the time by using:
then, Rob will take to complete the trip about 15 light-years.
hope this helps!!
A concave lens is used to form an image. The diagram shows three incident rays that pass the object and then reach the lens. How
does the lens affect the blue ray, which is incident on a path headed to the focal point on the right?
A. The ray bends outward on a path that traces back to the focal point on the left.
B. The ray bends so that it emerges from the lens travelling parallel to the axis.
C. The ray continues on its path and travels through the focal point on the right.
D. The ray bends outward on a path that traces back to the vertex of the lens.

Answer:
For the first situation, we first need to find the mass of the second train car.
In order to do that, we apply the conservation of the amount of movement:
and we have as a result:
m2 = 289.6875
For the second situation, also we will apply the conservation of the amount of movement:
and we have as a result:
V = 2.64 (it is moving to the right)
