What is the momentum of a 50 kg carton?

What is the momentum of a 50 kg carton?

A carton of mass 50-kg slides across an icy surface at a speed of 4 m/s. Conclusion : The momentum of a carton of given mass moving with a particular velocity is 200 kg − m/s .

What is the law of conservation of momentum?

The law of conservation of momentum states that in an isolated system the total momentum of two or more bodies acting upon each other remains constant unless an external force is applied. Therefore, momentum can neither be created nor destroyed.

What is the momentum of a 4 kg ball?

A 4 kg ball has a momentum of 12 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.

How to find momentum?

Step 1: List the mass and velocity of the object. Step 2: Convert any values into SI units (kg, m, s). Step 3: Multiply the mass and velocity of the object together to get the momentum of the object.

What is the formula of change in momentum?

Step 1: Identify the mass of the object, , the initial velocity of the object, , and the final velocity of the object, . Step 2: Calculate the change in momentum, which is equal to the impulse, , using the formula Δ p = m ( v f − v i ) .

Is momentum a scalar or vector?

For any physical system, the mass, momentum, and energy of the system must be conserved. Mass and energy are scalar quantities, while momentum is a vector quantity.

Is momentum always in kg?

The standard units for momentum are kg ⋅ m / s ‍ , and momentum is always a vector quantity. This simple relationship means that doubling either the mass or velocity of an object will simply double the momentum.

Is kg a unit of momentum?

The unit of momentum is the product of the units of mass and velocity. In SI units, if the mass is in kilograms and the velocity is in meters per second then the momentum is in kilogram meters per second (kgm/s).

What is the momentum of a 6.0 kg ball?

Expert-Verified Answer Mass of the ball = 6 kg. Velocity = 2.2 m/s. ∴ p = 13.2 kgms⁻¹. Hence, the momentum of the ball is 13.2 kgms⁻¹.

How much force does it take to move a 50 kg box?

It takes 350 N of horizontal force to set a 50 Kg box in motion across a floor. Once the box is in motion, a 325 N horizontal force keeps it moving at a constant velocity.

What is the momentum of an 8 kg?

Given , Mass (m) = 8 kg. Momentum (p) = 16 kg•m/s.

What is the momentum of a 1500 kg car?

Therefore p=1500*20 = 30,000 kg m/s.

What is the momentum of a 100 kg object at rest?

Answer and Explanation: The momentum of a 100kg boulder at rest is 0 kg*m/s. If we use our momentum equation p=mv, we can plug in the values from the problem with mass being equal to 100kg and velocity being equal to 0m/s. Velocity is equal to 0m/s because the boulder is at rest, or not moving.
