What is the momentum of a 5 kg object that has a velocity of 1.2 m/s?

P = 6 kg m/s

Explanation:

Momentum of an object is given by the product of mass and velocity. Any object in motion has momentum.

It is given by:

P = m v

where m is the mass and v is the velocity.

Here, m = 5 kg

v = 1.2 m/s

Thus, P = m v = 5 kg × 1.2 m/s² = 6 kg.m/s²

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.
