help with the following questions

Problem 1) Using the table of conversion factors on the inside front cover, convert (a) 760miles/h to m/s (b) 921kg/m3 to lb=/ft3 (c) 5.37103kJ/min to hp (d) 3 weeks to milliseconds (e) 38.1ft/s to miles/h (f) 554m4/( day kg) to cm4/(ming) Problem 2) A waste treatment pond is 50m long and 15m wide, and has an average depth of 2 m. The density of the waste is 85.3lbm/ft3. Calculate the weight of the pond contents in lbf. Problem 3) A frustrated professor once claimed that if all the reports she had graded in her career were stacked on top of one another, they would reach from the Earth to the moon. Assume that an average report is the thickness of about 10 sheets of printer paper and use a single dimensional equation to estimate the number of reports the professor would have had to grade for her claim to be valid. Problem 4) Calculate the following: (a) the weight in lbf of a 25.0lbm object. (b) the mass in kg of an object that weighs 25 newtons. (c) the weight in dynes of a 10-ton object (not metric tons). Problem 5) The stone is an English unit of mass ( I stone =14lbm, by definition) while the hand is a unit typically used to describe the height of a horse ( 1 hand =4 inches, by definition). You have a 1.00 gallon container completely filled with a fluid on the moon (acceleration of gravity = 1.63m/s2 or 5.35ft/s2 ). If the density of the fluid inside the container is 0.132 stone/hand how much does the fluid inside the container weigh (in pounds of force) on the moon
