If a spaceship has a momentum of 30,000 kg-m/s to the right and a mass of 400 kg, what is the magnitude of its velocity?
The momentum of the spaceship is given by the product of its mass and velocity. Therefore, the velocity of the spaceship can be calculated by dividing its momentum by its mass. In this case, the velocity would be 75 m/s to the right.
Is angular momentum a vector quantity?
Angular momentum is a vector quantity. Angular velocity, which is a vector quantity, is multiplied by inertia, which is a scalar quantity.
How can it be possible for two objects with different velocities to have the same momentum?
Two objects with different velocities can have the same momentum if one object has a greater mass and a lower velocity while the other object has a lower mass and a greater velocity. Because momentum is the product of mass and velocity, if the product of mass and velocity for each object is the same, their momenta will be equal.
Is momentum mass or velocity?
There are different types of momenta. What you are referring to is LINEAR momentum. Linear momentum is the product of an object's mass and linear (along a straight line: translational motion) velocity and is usually represented by 'p' : p = mv. Keep in mind that it is a vector quantity (has a magnitude and direction). Momentum represents the "amount of motion" of an object. Say you have two masses, m1 = m and m2 = 2m, so that m2 is twice as massive as m1. m1 is moving to the right at a linear velocity v1 = 2v and m2 is moving to the right at a linear velocity v2 =v. What are their linear momenta? Well, p1 = m1 v1 = 2mv and p2 = m2 v2 = 2mv, so that p1 = p2. So, although both objects have DIFFERENT linear velocities and DIFFERENT masses, their linear momenta ("amount of motion") for this case are the same. Now, if instead m1 is moving to the right at v1 = 3v and m2 is moving to the right at v2 = v, then: p1 = m1 v1 = 3mv p2 = m2 v2 = 2mv Although m1 is the smaller mass, it has a larger "amount of motion" compared to m2 for this case, because it's linear velocity is larger than the former case.
A 4000 Kg truck travels in a straight line at 10 meter per second then what is its momentum?
(Momentum) = (mass) x (velocity) If you know the momentum and the mass, you can find the velocity. Do you know how to do algebra? (velocity) = (Momentum) / (mass) = (30,000 kg m/s) / (400 kg) = 75 m/s

If a spaceship has a momentum of 30000 kg-ms to the right and a mass of 400 kg what is the magnitude of its velocity?
75 m/s "Apex"
A spaceship has a momentum of 45000 kg ms to the right and a mass of 200 kg What is the magnitude of its velocity?
Momentum = mass x speedSince Spaceship-#1 is not moving, it has no momentum. Their combined momentumis that of Spaceship-#2 alone.Momentum = mass x speed = 200 x 10 = 2,000 kilogram-meters per second.
Is angular momentum a vector quantity?
Angular momentum is a vector quantity. Angular velocity, which is a vector quantity, is multiplied by inertia, which is a scalar quantity.
Is the magnitude of instantaneous velocity always equal to the instantaneous speed?
Because speed is the magnitude of the velocity vector. The velocity consists of the speed and the direction, and the whole thing can be embodied in a 3D vector. If you like the velocity is the magnitude (the speed), which is a scalar (just a real number), multiplied by a unit vector in the right direction.
How can it be possible for two objects with different velocities to have the same momentum?
Two objects with different velocities can have the same momentum if one object has a greater mass and a lower velocity while the other object has a lower mass and a greater velocity. Because momentum is the product of mass and velocity, if the product of mass and velocity for each object is the same, their momenta will be equal.
A lioness has a mass of 180 kg and a velocity of 16 m per s to the right. What is her momentum?
Momentum =mv. The lioness has a momentum of 180 x 16 = 2880 kg m per s to the right.

In an isolated system bicycle 1 and 2 each with the mass of 30 kg collide bike 1 was moving to the right at 2 ms while bike 2 was moving to the left at 4 ms what is the magnitude of their momentum?
The momentum of an object is given by the product of its mass and velocity. The momentum of bike 1 is 30 kg x 2 m/s = 60 kg.m/s to the right, and the momentum of bike 2 is 30 kg x 4 m/s = 120 kg.m/s to the left. When bike 1 and bike 2 collide in an isolated system, the total momentum is conserved. The magnitude of their total momentum is 60 kg.m/s + 120 kg.m/s = 180 kg.m/s.
A 4000 Kg truck travels in a straight line at 10 meter per second then what is its momentum?
(Momentum) = (mass) x (velocity) If you know the momentum and the mass, you can find the velocity. Do you know how to do algebra? (velocity) = (Momentum) / (mass) = (30,000 kg m/s) / (400 kg) = 75 m/s
Why is angular momentum of a body is equal to the product of its moment of inertia and angular velocity?
Angular momentum about the axis of rotation is the moment of linear momentum about the axis. Linear momentum is mv ie product of mass and linear velocity. To get the moment of momentum we multiply mv by r, r the radius vector ie the distance right from the point to the momentum vector. So angular momentum = mv x r But we know v = rw, so angular momentum L = mr2 x w (w-angular velocity) mr2 is nothing but the moment of inertia of the moving body about the axis of rotation. Hence L = I w.
If an object is speeding up to the right what direction does its velocity vector point?
The velocity vector of an object that is speeding up to the right points in the same direction, to the right. Velocity is a vector quantity that includes both magnitude (speed) and direction, so as the object accelerates, the velocity vector will align with the direction of motion.
