How much force would be needed to move a car with a mass of 100kg to an acceleration of 5m/s/s?

500 newton force is needed to move a car of mass 100kg to an acceleration of 5m/s/s.

Explanation:

As we know from Newton's second law of motion that force= F = m×a

=> F = 100 × 5 = 500 N

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.
