The next 5 questiоns refer tо this scenаriо: A 10.0 kg box, stаrting аt rest slides down an incline. The first segment is 10.0 m long, inclined at an angle of 45º to the horizontal. The second segment is 15.0 m long, inclined at an angle of 30º to the horizontal. Along each segment, the coefficient of friction is 0.10. Note that: sin(30º) = 0.500 sin(45º) = 0.707 cos(30º) = 0.866 cos(45º) =0.707 Image Description Drawing of a left diagonal line with a bend in it. The first segment is 10.0m which is 45 degrees from horizontal. The continued next segment is 15.0m which is 30 degrees from horizontal.
