# FAQ: Which Is More Difficult To Stop A Tractor Trailer Truck?

## Which would take more force to stop in 10 seconds an 8 kg ball rolling in a straight line at a speed of 0.2 m/s or a 4 kg ball rolling along the same path at a speed of 1.0 m s?

v=28.6 m / s Which would take more force to stop in 10 seconds: an 8.0 – kilogram ball rolling in a straight line at a speed of 0.2 m / s or a 4.0- kilogram ball rolling along the same path at a speed of 0.1 m / s?

## What has a greater rest inertia?

Which substance has a greater rest inertia? The boulder, because it has a greater mass.

## What is the momentum of a 2000 kg car traveling at 20 ms?

. The momentum of a 2000 kilogram car traveling at 20 meters per second is: a. 0 kg •m/sec.

## What is the momentum of a 1900kg car that is sitting in the driveway?

8. What is the momentum of a 1900 kg car that is sitting in the driveway? Zero. The car is not moving (velocity is zero), therefore, the momentum is zero.

## What is the momentum of a golf ball with a mass?

Let’s calculate the momentum of the golf ball in the above example. If the golf ball has a mass of. 05 kg, and a velocity of 15 m/s, then what is its momentum? (Answer: momentum =. 05 kg*15 m/s= 0.75 kg m/s)

## How can a tennis ball and a bowling ball have the same momentum?

The force of gravity pull the balls down and changes its momentum. So, the tennis ball will change velocity more, but it has less mass, so it can have the same momentum change as the bowling ball, which will not affect velocity much but has a bigger mass.

## Which has more inertia bowling ball or tennis ball?

The greater the inertia (mass) of an object, the more force is needed to accelerate it at a given rate. Since inertia is simply just a measurement of mass, the bowling ball has a higher mass, thus inertia, than the tennis ball.

## What objects have the most inertia?

The bricks, like any object, possess inertia. That is, the bricks will resist changes in their state of motion. If Shirley gives them a push, then the bricks will offer resistance to this push. The one with the most mass will be the one with the most inertia.

## Do all the bodies have same inertia?

Answer. all bodies does not have same inertia because inertia depends on the mass of the body. For example it is easy to push or pull or stop a empty box or a book but it is not easy to push or pull or stop a car with the same force you used on the book or box.

## Which has more momentum a supertanker tied to a dock or a falling raindrop Why?

Momentum is a vector quantity, and the momenta of the two cars are in opposite directions. Which has more momentum, a supertanker tied at the dock or a falling raindrop? A falling raindrop because the supertanker at rest has zero momentum (assume it is not moving at all). You just studied 4 terms!

## How do you calculate momentum?

The Momentum Calculator uses the formula p=mv, or momentum (p) is equal to mass (m) times velocity (v). The calculator can use any two of the values to calculate the third.

## Can a bullet have the same momentum as a truck?

Yes, for a bullet to have the same momentum as a truck, it must have a higher velocity because the two masses are not the same.

## Is it possible for a motorcycle to have more momentum than semi truck?

Taking the formula for momentum to be p=mv this is the mass multiplied by the velocity. Although the semi truck certainly has a larger mass, it is not in motion and therefore does not have any momentum.

## What unit is momentum in?

Momentum is a measurement of mass in motion: how much mass is in how much motion. It is usually given the symbol p. Where m is the mass and v is the velocity. The standard units for momentum are k g ⋅ m / s mathrm{ kg cdot m/s } kg⋅ m/s k, g, dot, m, slash, s, and momentum is always a vector quantity.
