It says “Momentum before the collision is equal to momentum after the collision.” Elastic Collision formula is applied to calculate the mass or velocity of the elastic bodies.
A is correct.
When the car stereo is turned on, the chemical energy from the battery is transformed to electrical energy to make the stereo on, then the energy is transformed to sound so you can year it.
I am so sorry, but I do not know what section you are talking about. I hope you find the answer.
Answer:
Epot = 294300 [J]
Explanation:
Potential energy is defined as the product of mass by height by gravitational acceleration. The height is measured with respect to the reference level. At this reference level the potential energy is equal to zero.
where:
m = mass = 150 [kg]
g = gravity acceleration [m/s²]
h = elevation = 200 [m]
