If the mass of a cart full of groceries decreases to half and its speed doubles does the momentum double or quadruple?

The answer to the question is " no ", because neither of the permitted choices is correct.
Momentum = m V (mass times velocity)
There are no squares in that formula. Momentum is directly proportional to both mass and speed.
If mass is multiplied by 1/2 and speed is multiplied by 2, then the momentum is multiplied by
(1/2) x (2) = 1
The momentum doesn't change.

What happens to the surface area of a cylinder if the diameter of the base is doubled and the height is not changed?
The base areas quadruple and the curved surface doubles.
What happens to the circumference of a circle when the radius doubles?
If the radius of a circle doubles, the circumference doubles, and so does the diameter.
What happens to the circumference of a circle when the radius is doubles?
The circumference also doubles.
What happens to the area of a rectangle if the width doubles?
The area also doubles.
What will happen if the diameter of the circle doubles how will the circumference change?
The circumference also doubles.
If the mass of a cart full of groceries decreases to half and its speed doubles what happens to the momentum of the cart?
if you add more weight or mass to any thing, it will incease its momentum. lets say you are grocery shopping and you add 5 bags of cat liter to your cart. inertia will increase and your momentum will increase. it easy, just picture it in you head. your welcome!!!!
What happens to momentum when velocity doubles?
Momentum is equal to the product of mass and velocity, so either the mass halves or the momentum doubles.
If mass doubles what happens to momentum?
If mass doubles, momentum stays the same, but the velocity is half. momentum = mass * velocity mass1 * velocity1 = mass2 * velocity2
How about if the velocity is doubled but the mass remains the same?
Momentum is a simple product of mass time velocity. So if the velocity doubles the momentum doubles.
What happens to the momentum if the mass of the object increases?
The momentum will increase in this case.The momentum will increase in this case.The momentum will increase in this case.The momentum will increase in this case.
If the speed of a moving object doubles then what else doubles?
Its momentum (defined as mass x velocity).
When the rotational speed of a rotating system doubles its angular momentum?
Gets doubled
What happens to the surface area of a cylinder if the diameter of the base is doubled and the height is not changed?
The base areas quadruple and the curved surface doubles.
What happens to the pressure of a confined gas at a constant temperature when the volume is reduced by half?
pressure decreases
How kinetic energy of an object changes when the speed of an abject doubles?
Assuming non-relativistic speeds: Doubling the speed will quadruple the kinetic energy.
If the mass of a moving object is doubled with no change in velocity what would be the change in momentum?
It doubles. Momentum (p) is the product of velocity (v) and mass (m). For a given mass, if you double the velocity, you'll double the momentum. Velocity and momentum are said to be directly proportional. p = m x v
What happens to mass if volume is tripled?
You just double it or square it or times it by 2 or just sit there and stare at the screen......hhahahahahaahahhaha
