Both cars are canceling out the energy of each other. The energy that is left over because one car has a bigger kinetic energy is the energy that is going to move BOTH the cars.
First Car : <em>0.5 * 2000kg * 3m/s^2 = 10.24 KJ</em>
Second Car :<em> 0.5 * 2000kg * 2m/s^2 = 4 KJ</em>
Leftover Energy : <em>10.24 KJ - 4 KJ = 6.24 KJ
</em>
Movement of BOTH cars :<em /><em>
6.24 = 4000kg * v^2
</em>v = √(6.24 / 4000) =0.04 m/s = 4 cm/s
Answer:
kinetic energy, form of energy that an object or a particle has by reason of its motion.
potential energy, stored energy that depends upon the relative position of various parts of a system
Answer:
8.9m/s
Explanation:
Final velocity = initial velocity + acceleration *time
Vf=vi+at
Vf=1.4 m/s
Vi=?
A=-2.5m/s^2
T=3
1.4m/s=vi+(-2.5m/s^2)(3s)
Vi=8.9m/s
<u>Explanation:</u>
In other to avoid a situation where their differences, pride, and personalities caused them to compete and publicly insult one another instead of working together they need to respectfully consider the viewpoints of each other, as well as assign individual roles that should be respected.
A device that uses electromagnetic induction to transfer electrical energy from one circuit to another is a transformer.
<h3>Which device uses electromagnetic induction to transfer electrical energy from one circuit to another?</h3>
- A transformer is an electrical device that transfers energy from one electric circuit to another using the electromagnetic induction principle.
- It is intended to change the AC voltage between the circuits while keeping the current's frequency constant.
- A transformer work on the principle of electromagnetic induction in which flux is linked from primary to secondary.
- Transformers accomplish this without establishing a conductive link between the two circuits. This is made feasible by using Faraday's Law of Induction, which explains how an electric circuit will interact with a magnetic field to produce an electromotive force (EMF).
