A person pulls horizontally on block B , causing both blocks to move together as a unit. While this system is moving, make a carefully labeled free-body diagram of block A if
(a) The table is frictionless
(b) There is friction between block B and the table and the pull is equal to the friction force on block B due to the table.​

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
