A car has a mass of 1.00 × 103 kilograms, and it has an acceleration of 4.5 meters/second2. What is the net force on the car
Novay_Z [31]

Answer:

4.5 *10^{3}\ kgm/s^{2}

Explanation:

Given:

Mass= 1.00 * 10^{3} \ kilograms,\\Acceleration =4.5\  meters/second^{2}

As we know that

Force=Mass * Acceleration

Putting the value of mass and Acceleration  we get ,

Force\  = \ 1.00 * 10^{3} * 4.5\ m/s^{2}

Force\  =4.5 * \ 10^{3} \  kgm/s^{2}

Therefore Net force is :4.5 *10^{3}\ kgm/s^{2}

A girl takes her dog for a walk on a sunny beach. Find the force of gravity between the 45-kg girl and her 11-kg dog when they a
Lady_Fox [76]

The gravitational force acting between them is 8.25*10^-^9N

Data given;

  • M1 = 45kg
  • M2 = 11kg
  • r = 2.0m
  • G = 6.67*10^-^1^1m^3kg^-^1s^-^1

To solve this question, we need to apply gravitational force or energy formula.

<h3>Gravitational Force</h3>

This states that the force of attraction between two bodies is equal to the product of their bodies and inversely proportional to the square of their distance apart.

Mathematically;

F = \frac{GM_1M_2}{r^2} \\

let's substitute the values and solve

F = \frac{Gm_1m_2}{r^2}\\F = \frac{6.67*10^-^1^1 * 45 * 11}{2^2}\\F = 8.25*10^-^9N

The force of gravity acting between them is 8.25*10^-^9N
