The solved solution is in the attach document.
If the truck moves at same speed but twice as much mass, its momentum is increased twice.
Answer:
Explanation:
Momentum is defined as the force experienced by any object for a given time. In other words, it is the measure of the mass and velocity required for a certain motion. So it is determined as the product of mass and velocity of any object.
Momentum = Mass × Velocity.
As momentum is directly proportional to both mass and velocity, increase in any one of these two quantities keeping the other constant will lead to increase in the momentum.
So in the present case, it is stated as speed is kept constant and the mass is increased twice, then the momentum will also increase twice.
New momentum = 2 ×mass × velocity = 2 × old momentum
If the truck moves at same speed but twice as much mass, its momentum is increased twice.
The three main points of the kinetic theory of matter<span> are all </span>matter<span> consists of molecules and atoms; these molecules and atoms are constantly moving around; and as the temperature increases, the speed of the particles, and therefore the energy of the </span>matter<span>, increases.</span>
