Two vehicles collide and stick together. after the collision, their combined y-momentum is 2.40 × 104 kilogram meters/second, and their x-momentum is 7.00 × 104 kilogram meters/second. what is the angle of the motion of the two vehicles, with respect to the x-axis? a)16.8° b)17.0° c)18.9° d)20.8° e)21.8° just let know if its a-b

Answer : What is the angle of the motion of the two vehicles, with respect to the x-axis is 18.9°

Explanation :

Given that,

Two vehicle collide and stick together. This shows an inelastic collision.

Momentum in y direction,  

Momentum in x direction,      

Since the momentum is vector quantity so the angle between them is given by :

So, the correct option is (C) " 18.9° "
