i tried it before. 84+8+3=95 it still didn't work..:(

Work is force*distance then i did 19*10=190 it doesn't work

A 10 kg cart is pulled by a force of 12 Newtons for a distance of 7 meters, then by a force of 4 Newtons for 2 meters, then it is pushed (slowed down) by a force of 3 Newton for 1 meters. All this occurs on a horizontal surface. A)Initially assuming the surface to be frictionless, what net...

I have the same problem...dx=40cm, m=8kg, F=25N I figured K=62.5 I used what you explained. (1/2)(62.5)(.4m) - (1/2)(62.5)(.2m)=6.25 don't i plug that in v=sqrt((6.25(.2^2))/8) to find the velocity halfway? i am not getting it right! I probably pluged in something wrong obviously. please help.
