  • The motion of a ball falling through the atmosphere, or a model rocket being launched up into the atmosphere are both excellent examples of Newton’s 1st law of motion.

  • Riding a bicycle is a good example of Newton’s 2nd law of motion.In this example, the bicycle is the mass. The leg muscles pushing on the pedals of the bicycle is the force.

  • You hit a wall with a certain amount of force, and the wall returns that same amount of force. This is an example of Newton’s 3rd law of motion

A 100 kilogram person acquires a velocity of 15 meters per second down a ski slope.What is the skier's kinetic energy?
azamat

11250J

Explanation:

Given parameters:

Mass of the person = 100kg

Velocity = 15m/s

Unknown:

Kinetic energy  = ?

Solution:

The kinetic energy of a body is energy due to the motion of the body.

 Kinetic energy = \frac{1}{2} m v²

    m is the mass of the body

    v is the velocity

  Substituting the parameters:

     

 K. E =  \frac{1}{2} x 100 x 15² = 11250J

When an object is fully converted into energy the amount of energy liberated is
EleoNora [17]

Answer:

Mass, m = 4 kg

Explanation:

<u>Given the following data;</u>

Energy = 3.6 * 10^17 Joules

We know that the speed of light is equal to 3 * 10⁸ m/s.

To find the mass of the substance;

The theory of special relativity by Albert Einstein gave birth to one of the most famous equation in science.

The equation illustrates, energy equals mass multiplied by the square of the speed of light.

Mathematically, the theory of special relativity is given by the formula;

E = mc^{2}

Where;

  • E is the energy possessed by a substance.
  • m is the mass.
  • c is the speed of light.

Substituting into the formula, we have;

3.6 * 10^{17} = m * 300000000^{2}

3.6 * 10^{17} = m * 9*10^{16}

m = \frac {3.6 * 10^{17}}{9*10^{16}}

Mass, m = 4 kg
