1.The natural water of a sample taken from a soil deposit was found to be 11.5%. it has been calculated that the maximum density for the soil will be obtained when the water content reaches 21.5%. Compute how many grams of water must be added to each 1000g of soil( in its natural state) in order to increase the water content 21.5 %.

2.A driver is traveling at 52 mi/h on a wet road. an object is spotted on the road 415 ft ahead and the driver is able to come to a stop just before hitting the object. assuming standard perception/ reaction time and practical stopping distance, determine the grade of the road.
