A 50 kg ball rolls down the street at 5 m/s.
Calculate the momentum of the ball.

The momentum of the ball is 250 Kgm/s

Given the following data;

To find the momentum of the ball;

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. It is a vector quantity and as such has both magnitude and direction.

Mathematically, momentum is giving by the formula;

Substituting into the formula, we have;

Momentum = 250 Kgm/s

Therefore, the momentum of the ball is 250 Kgm/s

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

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.
