Assume that the density of the building material is 5000kg / m 3 and that the gravitational acceleration is 10m / s 2 . a) Calculate the work needed to construct the ramp. b) How long will it take at least to construct this ramp if one uses a 10 horse power machine to lift the material ? (1 horse power =750 Watts). IV: (25 points) Consider the region R that is bounded above y = 2-x , below by the x axis and on the side by x = 0 and x = 1. a) Calculate the volume of the solid that is generated by rotating R about the y axis. b) Calculate the volume of the solid generated by revolving the region R about the x axis....
