- Find the center of mass of a thin plate of constant density covering the region bounded by the parabola y = 2x and the line y = 8. The center of mass is locatod at (x. ) =D (Simplify your answer. Type an ordered pair.)arrow_forwardA light bulb is designed by revolving the graph of y = tzi - rł, oarrow_forwardThe 0.50 lb ball is shot from the spring device shown. The spring has a stiffness k = 10 lb/in. and the four cords C and plate P keep the spring compressed 2 in. when no load is on the plate. The plate is pushed back 3 in. from its initial position. (Eigure 1) If it is then released from rest, determine the speed of the ball when it travels 23 in. up the smooth plane. Express your answer to three significant figure and include the appropriate units.
