Unformatted text preview: Nicholas Charles Miller- PHY183, Spring 2010 - Physics for Scientists and Engineers I 1 Homework Set 7 Due date: Sun Mar 21 23:59:00 2010 L L / 4 L 4 L x y Assume that we have a uniform, square metal plate with side L = 8.60 cm and mass 0.205 kg. The plate is located with its lower left corner at (x,y) = (0,0) as shown in the figure. We remove a square from of the plate with side L /4 with lower left edge located at (x,y) =(0,0). What is the distance of the center of mass of the remaining plate from the origin? Tries 0/99 Suppose we have a rocket in outer space. The rocket consists of a payload of 4380.0 kg and 140900.0 kg of fuel. Assume that the rocket starts from rest, accelerates to its final velocity, and then begins the trip. What is the speed at which we must expel the propellant to make the trip from the Earth to the Moon, a distance of 3.82 x 10 5 km, in 7.5 hours? Tries 0/99 Shown is a stack of identical aluminum blocks of length l = 18.9 cm and thickness d = 2.0 cm, stacked on a table. If= 2....
