) State the relation between acceleration and momentum (10 marks). (B) Two small steel balls A and B have mass 0.6 kg and 0.2 kg respectively. They are

moving towards each other in opposite directions on a smooth horizontal table when they

collide directly. Immediately before the collision, the speed of A is 8 m/s and the speed of B

is 2 m/s. Immediately after the collision, the direction of motion of A is unchanged and the

speed of B is twice the speed of A. Find :

a. The speed of A immediately after the collision (10 marks),

b. The magnitude of the impulse exerted on B in the collision​

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

What is the measurement of how fast an object moves relative to a reference point?
