If y 0 m for gravitational potential energy is the horizontal surface, what is the work done by non- conservative forces if, after it has slid some distance, it stops? Answer in Joules and if the answer is negative include a negative in your answer Question 3 10.5 pts of 6 kg is moving at 38 m/s ona horizontal surtace and the enitre surtace bos triction with a coefficient ot kineric tuction ot 0 54 1t-0 m for rvtalenal potenti) tor does the oDieet side before it stops in metersExplanation / Answer
Work done = change in KE (work - energy theorem)
= Kf - ki
= 0 - (7 x 6.6^2 / 2)
= - 152.5 J
