A mass of 9 kg with initial velocity 10 m/s travels through a wind tunnel that exerts a constant force 8 N for a distance 2m. It climbs a frictional incline of height 3 m inclined at an angle 12, then moves along a second frictional surface of coefficient 0.19 before coming to rest. The acceleration of gravity is 9.8 m/s2 . If the first frictional surface has a coefficient of 0.21 for a distance 0.5 m, how far does it slide along the second frictional region before coming to rest?
