well the work done by the hand must become thermal energy because of the presence of friction so it must transfer into the surface its sliding acrossed

well it probably has something to do with that equation from before but it must have to do with distance and force

however in this problem i do not have a mass to use

now were on to d) which I am still confused i would usually do 1/2 x m x v^2

sorry i figured out C tho i realized that its relative to friction work done the answer is 2.4

well i know thermal energy is based off of the friction

ahhh oh yes that was my bad sry

however i would like assistance with the second half of the problem that would be awesome because that is the only part I am confused on

um i know that the answer is right because this is on a web assign that my teacher assigned i understand i left the negatives out but i just add the negative into the final answer rather than thinking about the negative prior to that

the 2 things i added are the answers to the first two parts of the question for what is the work done by friction and just work done overall

i added what i have so far can u help me solve the rest please

Homework Statement A block starts at rest. A hand pushes the block with 6.1 N to the right across a rough surface, with 1.5 N of friction. if the block moves 1.6 m horizontally determine the following (a) work done by hand (b) work done by friction (c) the amount of thermal energy created (d)...
