Figure shows a 11.7 ft wide ditch with the approach roads at and angle of 15^0 with the horizontal. With what minimum speed should a mororbike be moving on the road so that it safely croses the ditch? Assume that the length of thebike is 5 ft, and it leaves the road when the front part runs out of the approch road.
