A bumper car with a mass of 200 kilograms traveling at a velocity of 3.5 meters/second collides with a stationary bumper car with a mass of 250 kilograms. the kinetic energy of the system after the collision is 1190,25 J.
The energy is the ability to work or produce action or movement and it manifests itself in many different ways mostly body movement, heat, electricity, etc.
The different types of energy are Kinetic energy is associated with the movement of bodies. Potential energy which is stored form of energy by virtue of a body's position relative to its surface is also called gravitational potential energy.
Thermal Energy associated with the kinetic energy of the molecules that make up an element, Chemical energy released from chemical reactions, Solar energy released from sunlight.
Ek = (m·V²)/2
V - velocity of system after the collision
m = m1 + m2
Ek = (m1 + m2)·V²/2
Ek = (200 +250)·2,3²/2 = 450·5,29/2 = 1190,25 J

Reflection is the answer
Answer:
Explanation:
Expression for relative velocity
=
= (.54 + .82 )c/
= 1.36 c / 1.4428
= .94 c
β = .94
b. no waste
c. radioactive waste that can be released into local water supplies
d. air pollution
Nuclear power plants produce radioactive waste that must be stored properly in other to prevent pollution and health hazards.
Nuclear power plant refer to the thermal power station in which power is generated and the the heat source is a nuclear reactor. In any thermal power stations, heat is used to generate steam that spin up steam turbine connected to a generator that produces electricity.
Therefore, Nuclear powerplants produce radioactive waste that must be stored properly.
