An object whose mass is 330.693 lb experiences changes in its kinetic and potential energies owing to the action of a resultant force R. The work done on the object by the resultant force is 163 Btu. There are no other interactions between the object and its surroundings. If the object’s elevation increases by 90 ft and its final velocity is 150 ft/s, what is its initial velocity, in ft/s? Let g = 32.2 ft/s^2. Ans. V1 = 60.10 ft/s
