HELP!!! energy and work TROUBLE!! ....im very worried about my current lesson in class because it has me completely stumped! One questions asks.... Two objects move with different masses from rest and are pulled by the same magnitude net force and move through the same distance while the force acts on them. The work done on object 1 is 500 Joules (Nm). After the force has pulled each object, object 1 is moving twice as fast as object 2. Answer the following questions, showing your work. (a) How much work is done on object 2? (i put the same amount, since the force and distance are the same in both, then work must be equal) (b) What is the kinetic energy of object 1 AFTER being pulled? (this stumped me and i have no idea where to start) (c) What is the kinetic energy of object 2 after being pulled? (i have no idea how to do c since b stumped me... ) (d) If the mass of object 1 is 20 kg, what is the mass of object 2? (i put 20 kg for this answer, and i have no idea, nor formula, to show how i got it) I NEED HELP!!! If u can help in ANY WAY please post a message for me! also, if u have useful links about this topic if u can post them i would really appreciate it! THANKS!
