<u>KINETIC ENERGY</u></h2>
<h3>Problem:</h3>
» Kinetic energy of 35 J and a mass of 34 kg, how fast is the object moving?
<h3>Answer:</h3>
— — — — — — — — — —
<h3>Formula:</h3>
To calculate the velocity of a kinetic energy, we can use formula
where,
- v is the velocity in m/s
- KE is the kinetic energy in J (joules)
- m is the mass in kg
Based on the problem, the givens are:
- KE (Kinetic energy) = 35 J
- m (mass) = 34 kg
- v (velocity) = ? (unknown)
<h3>Solution:</h3>
To get the velocity, substitute the givens in the formula above then solve.
Therefore, the velocity is 1.435 m/s.
light is "visible". thermal can be infrared just beyond visible
<span>The thruster releases
small amounts of substance (in the form of a gas or liquid) at very high speed
out of the nozzle. Since Newtons 3rd
law states that each action has an equal and opposite reaction, therefore
spacecraft should also experience a push in the opposite direction</span>. Therefore
the spaceship will move. This will only stop when it faces an equal opposite
force.
Answer:
<span>c. the spaceship will move and will not stop until it is
stopped by an equal and opposite forced</span>
