The momentum p of an object of mass m and speed v is

p = mv

The kinetic energy K of the same object is

K = 1/2 mv^2 = p^2 / 2m

Lets say the truck has velocity V and mass M, and the bike has velocity v and mass m < M. If their momentum is the same, this means

mv = MV

therefore v is greater than V since m is less than M. v^2 is therefore MUCH greater than V^2,so the kinetic energy of the bike is much greater than the kinetic energy of the truck. This means that it takes more energy to stop the bike than it does to stop the truck.

How can a racing bicycle have the same linear momentum as a pickup truck?

Momentum = mass x velocity The bike has a much smaller mass, but if its velocity is great enough and the truck's is slow enough, the product can be the same. mass(bike) X Speed(bike) = mass(truck) X speed(truck) for an example, Speed(x)=0 and speed(x)=0 therefore, the two momentums are equal.


Which truck has more momentum a 2000kg truckor a 2kg truck?

That would depend on their velocity (speed with direction), since the formula for momentum is momentum=Mass*Velocity. If they are moving at the same Velocity, the heavier of the two would have greater momentum.


Which has more momentum heavy truck light truck or do they both have the same momentum?

A truck that is more massive with the same velocity as the truck that is less massive will definitely have more momentum. This is illustrated in the equation for momentum:p = mvWhere p is momentum which is measured in Newton seconds, m is mass which is measured in kilograms, and v is velocity, measured in meters per second. If you plug in a larger mass for that same equivalent velocity, it will accordingly have more momentum.Also, if you just think about it, what would be harder to move: something with more mass or something with less mass?


Why it is easy to stop moving bicycle then the moving car with same speed?

It is easier to stop a bicycle than a car with the same speed because the bicycle has less mass and momentum compared to the car. The car's greater mass and momentum make it harder to stop quickly. The car's brakes also have to work against greater inertia, requiring more force and distance to stop.


Is it possible for a bullet to have the same momentum as a truck?

Yes, it is possible for a bullet to have the same momentum as a truck if the bullet is traveling at a much higher velocity than the truck. Momentum is calculated as mass times velocity, so a small object like a bullet can have the same momentum as a larger object like a truck if its velocity is much greater.

Why does a semi truck have more momentum than a bicycle?

A parked semi truck has no momentum. A moving bicycle does. If both the bike and the truck are moving at the same speed in the same direction, the truck will have more because it has more mass.


If a truck and a bike have the same momentum which would be harder to stop a truck or a bike?

When can a car and truck have the same momentum?

Momentum is the product of mass x velocity, so if this product is the same for both, they will have the same momentum.

If a car and a truck are traveling at the same speed, the truck would have more momentum because it has a greater mass.

When a toy truck collides into a toy car the momentum of the what is the same before and after the collision?

The total momentum of the system doesn't change. In this case, it refers to the momentum of the toy truck plus the momentum of the toy car.


Does a truck have more momentum than a car?

Yes. At the same velocity, a truck would have more momentum than a car as it has greater mass. Momentum is the product of mass and velocity: &rho;=mv
