Arace car enters the circular portion of a track that has a radius of 63 m. when the car enters the curve at point p, it is travelling with a speed of 120 km/h that is increasing at 5 m/s2.

When car enters a circular path its speed is increasing at rate 5 m/s^2

so this is the tangential acceleration of car

now at the same time since car is moving along the curved path so it must have centripetal acceleration at the same time

It is given by equation

so now the net acceleration of the car is given as

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.
