87. The magnitude of the downhill component of the gravitational force acting on each ore car is= 100009.82wxkgm / s sinbgchθwhere= 30° (and it is important to have the calculator in degrees mode during this problem). We are told that a downhill pull of 3ωxcauses the cable to stretch x= 0.15 m. Since the cable is expected to obey Hooke’s law, its spring constant is =3= 9.8 10
