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?

Explanation:

It is given that,

Momentum in y direction is

Momentum in x direction is

We need to find the angle of the motion of the two vehicles, with respect to the x-axis. The angle between two vectors is given by :

So, the angle of the motion of the two vehicles is 18.88 degrees.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
