Question

please help me. double and triple check your answers, previous tutors got it wrong. this is  a practice problem, not for a grade. i attached the question in one screenshot, and my previous incorrect answers as another.

 

this is part c so what i got outta part A and B is  the minimum value of the coefficent is 0.49 and the answer to part b which asked, As the snow begins to melt the coefficient of static friction decreases and the snow finally slips. Assuming that the distance from the chunk to the edge of the roof is 6.0 mm and the coefficient of kinetic friction is 0.17, calculate the speed of the snow chunk when it slides off the roof, is 5.8 m/s
