Answer:
the speed of the center of mass of the two-particle system is 3.4 m/s.
Explanation:
Given that,
Mass of particle 1, m = 2 kg
Velocity of the particle 1, v = 4 m/s in +x direction
Mass of particle 2, m' = 3 kg
Velocity of the particle 2, v' = 5 m/s in +y direction.
The x -coordinate of velocity of the centre of mass is given by :
The y -coordinate of velocity of the centre of mass is given by :
So, the the speed of the center of mass of the two-particle system given by :
So, the speed of the center of mass of the two-particle system is 3.4 m/s.
Answer:
Add
Explanation:
When two forces are acting in the same direction then there magnitude are added to each other
Let the first force is and second force is and when they act in same direction then their equivalent will be equal to
When they cat in opposite direction then their equivalent will be
Answer:
The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.
