How much work would it take to horizontally accelerate an object with a mass of #8 kg# to #7 m/s# on a surface with a kinetic friction coefficient of #2 #?
Wrong question ..?
For the body to be accelerated to 7
we know , work don't in doing so is equal to
This can be altered due the presence of friction force.
To solve this question we have to get at least 1 variables , But here we have got 2 , provided the information is insufficient.
