The 100-lb platform rolls without slipping along the 10 degree incline on two pairs of 16-in.diameter wheels. Each pair of wheel
s 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?

Answer:11.602 KW
Explanation:
mass of vehicle
speed=40Km/h
Resistance=600 N
Gear ratio
Net force to overcome by engine is
F=Resistance + sin component of weight
F=600+
Where
F=600+235.38=835.38 N
power=
Engine Power==11.602 KW
