What is an object of mass 2kg has a linear momentum of magnitude 6kg?

What is an object of mass 2kg has a linear momentum of magnitude 6kg?

The magnitude of the object’s linear momentum is p=mv. If p=6kg⋅m/sandm=2kg, then v=3m/s. therefore, the object’s kinetic energy is K=12mv2=12(2kg)(3m/s)2=9J.

What is the speed of the block immediately after the bullet exits?

The block rests on a frictionless surface, and is thin enough that the bullet passes completely through it. Immediately after the bullet exits the block, the speed of the block is 23 m/s.

What is the linear momentum of a body of mass 5 kg is moving with a velocity of 2 meters per second?

momentum = 5×2 = 10 kg m/s.

What is the formula for momentum in kg?

In symbols, linear momentum p is defined to be p = mv, where m is the mass of the system and v is its velocity. The SI unit for momentum is kg · m/s. Newton’s second law of motion in terms of momentum states that the net external force equals the change in momentum of a system divided by the time over which it changes.

At what point is a bullet the fastest?

For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.

How fast do bullets slow?

Once the gases stop pushing it, it begins to slow down due to two forces – the resistance of the air that it’s pushing through, and the downward suck of gravity. Typically, a bullet will take around 30 seconds to climb to a height of around three kilometres, at which point it has a velocity of zero. Then it falls.

Do bullets travel fast?

When bullets fly through the air, they do so at amazing speeds. The fastest bullets travel more than 2,600 feet per second. That’s equivalent to over 1,800 miles per hour.

What is momentum its SI unit?

SI Unit of Momentum As mentioned above, the units of momentum will be the product of the units of mass and velocity. Mass is measured in kg and velocity in ms-1, therefore, the SI unit of momentum will be kgm/s(-1).

What is the linear momentum of a body of mass 10 kg moves with velocity 5 Metre per second?

Answer: The linear momentum of a body of mass 10 kg moving with velocity 5 m/sec is 50 kg m/s.

What is the linear momentum of a car of a mass of 1000 kg?

Momentum of the car is : P = m×v =1000×10=10000kgm/sec. Was this answer helpful?

What magnitude impulse will give a 2.0 kg object a momentum change of magnitude +50 kg ∙ M S?

What magnitude impulse will give a 2.0kg object a momentum change of magnitude +50 kgm/s? The answer is +50Ns, can someone explain this showing work?

What is the acceleration of a 6 kg object?

A 6-kg object experiences an acceleration of 2 m/s/s. 2. A net force of 15 N is exerted on an encyclopedia to cause it to accelerate at a rate of 5 m/s2.

What is the kinetic energy of the linear momentum of a body of mass 2kg is 16 kgm s?

So, the kinetic energy of the body is 64 J.

What is the linear momentum P of a body of mass 2kg varies with time?

Given: Mass = 2 Kg, linear momentum varies with time as P = 3t² + 4.
