If you have a Corvette with a mass of 1,054 kg and a velocity of 48m/s, find the kinetic energy in J.

Yes, there a possibility that the momentum of one object is not conserved.

Newton's third law suggests that momentum is always conserved in collisions between two isolated objects. In collisions, it is believed that the interaction between the colliding items lasts for a brief period of time, making the impulse caused by outside forces insignificant.

For the momentum to be conserved, a system must satisfy two conditions:

Throughout the interaction, the system's mass must remain constant.

The system must be subject to zero net external force.

Momentum does not always change and is not conserved because the collision is automatically conserved when the kinetic energy is. The amount of momentum needed when there is a change in speed during a collision remains constant.

The Right Hand Thumb Rule, which asserts that if the thumb is kept pointing in the direction of the current, the curl of the other fingers indicates the direction of the magnetic field, is along the eastern direction if the current is flowing to the north.

The right hand rule is a hand mnemonic in physics that is used to remember which way three-dimensional axes or parameters point. The right hand rule was developed in the 19th century by British physicist John Ambrose Fleming for electromagnetism applications. When the other two parameters are known, it is most frequently employed to identify the direction of the third parameter (magnetic field, current, magnetic force).

The right hand rule has a few modifications, which are described in this section. A conductor, like a copper wire, induces an electric current when it passes through a magnetic field (B). Faraday's Law of Induction is the name given to this phenomenon.

The answer is  2.416 m/s^2.

Solution:

friction force on the upper block = umg

= 0.13*2*9.81

= 2.5506 N

so writing the equation of motion for the upper block

T - f = ma

or T-2.5506 = 2a

writing the equation of motion for the lower block

mg-T=ma

or 9.8-T=a

Hence, we get a  = 2.416 m/s^2.

Since the top block slides to the right, the frictional force acting on it acts to the left. His reaction wall acts on the forward-acting lower block. The frictional force absorbs x mechanical energy from the upper block, but transfers only y mechanical energy to the lower block. To find the acceleration of the body in terms of angle and coefficient of friction.

A material modulus value of 1 means that the friction force is equal to the normal force. This means that the force required to move an object is equal to its weight.

What is frictional force?

Frictional force is defined as the force that opposes motion when one body's surface comes into contact with the surface of another. Friction force reduces a machine's mechanical advantage, or the ratio of output to input. An automobile uses about one-quarter of its energy to restrict friction force, but friction in the tyres keeps the car on the road, and friction in the clutch allows us to drive.

Friction is one of the most prevalent phenomena in the physical universe, affecting everything from matchsticks to machines to the molecular structures of every simple and complex object.

Frictional force is the opposing force formed when two surfaces attempt to move in the same direction or in opposite directions. A frictional force's primary function is to generate resistance to the mobility of one surface over another. The frictional force is determined by the texture of the body's surface.

The total kinetic energy of the system of the two objects can be achieved by adding of the kinetic energies of first and second body.

Kinetic energy is directly proportional to the mass of the thing and to the square of its velocity: K.E. = 1/2 m v². If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared. So the formula for kinetic energy is that it's equal to 1/2 times the mass of the object, times the immensity of its velocity squared, or another way to think about it, its speed squared. In an elastic collision, both the impulse and the kinetic energy of the system are maintained. On the other hand, in an inelastic collision, momentum is sustained but kinetic energy can not be sustained.
