The 100-lb platform rolls without slipping along the 10 degree incline on two pairs of 16-in. diameter wheels. each pair of wheels with attached axle weighs 25 lb and has a centroid radius of gyration of 5.5 in. the platform has an initial speed of 3 ft/ sec down the incline when a tension t is applied through a cables attached to the platform. if the platform acquires a speed of 3ft/sec up the incline after the tension has been applied for 8 seconds, what is the average value of the tension in the cable?
