The si unit of force is newton.
so, F is eqal to m*g
Answer:
The y-component of the car's position vector is 670m/s.
The x-component of the acceleration vector is -3, and the y-component is 40.
Explanation:
The displacement vector of the car with velocity

is the integral of the velocity.
Integrating
we get the displacement vector
:

Now if the initial position if the car is

then the displacement of the car at time
is


Now at
, we have

The y-component of the car's position vector is 670m/s.
The acceleration vector is the derivative of the velocity vector:

and at
it is

The x-component of the acceleration vector is -3, and the y-component is 40.
The overall charge on a neutral atom is zero.
A neutral atoms contains equal number of electrons and protons.The charge of a proton and electron is equal in magnitude but opposite in sign. A proton has a charge of 1.6 x 10⁻¹⁹C and the charge of an electron is -1.6 x 10⁻¹⁹C. Thus in a neutral atom, the charge of all the protons gets cancelled with the charge of all the electrons.
Thus a neutral atom has a net zero charge.
