Answer:
D is the answer hope you it helps you
Explanation:
It is given that,
Mass of the car 1,
Initial speed of car 1, (east)
Mass of the car 2,
Initial speed of car 2, (north)
(b) As the cars stick together. It is a case of inelastic collision. Let V is the common speed after the collision. Using the conservation of momentum as :
The magnitude of speed,
V = 12.22 m/s
(b) Let is the direction the wreckage move just after the collision. It is given by :
Hence, this is the required solution.
I am so sorry, but I do not know what section you are talking about. I hope you find the answer.
