PLEASSSEEE HELPLPP Explain Two objects are moving downward at a speed of 3 cm/s. Object A has a mass of 2 kg and Object B
has a mass of 1 kg. You want both objects to move to the left at a speed of 3 cm/s.

1. In what direction (or directions) should you exert the forces that will make the desired change?
force direction(s):
2. Describe what strength force or forces would be needed to cause the desired velocity change:
Make Object A and Object B move to the left at 3 cm/s.
3. After you finish, answer the reflection questions on your Amplify Science screen.

Ok i am attempting to my niece attach a galvanized wire (like a tether for a dog) at the corner of two fences, making a tightwire if you will and we drilled a hole in a softball and she hits it. the ? and problem is that we can not get the wire taunt enough where it doesnt sag after hitting the ball once, and the wire sags and wobbbles. its a 15 ft rubber covered galvanized wire and one can adjust the length of the placing of the wire by having it make the corner of 2 fences become a it can be adjusted, however, with all our human strength and pliers we could not make it taunt as possible. is there anything other that attaching it to a car to do this. sorry abt the length but it would mean the world to my niece if i could solve this came up with the entire idea herself, and she is 14 and paid for the wire and did as much work as i did drilling a hole through a softball wide enough for attaching piece at each end of the wire that clips on to the fence. . any ideas welcome if serious. but awesome if it is a fact. much obliged. bucky bukowski buckman

A1kg cart slams into a stationary 1kg cart at 2 m/s. the carts stick together and move forward at a speed of 1 m/sl. determine whether kinetic energy was conserved in the collision. use the law of conservation of energy to explain the collision

What is the scientific definition of energy that relates to work
