Consider a system made up of three point particles m1 = 1 kg, m2 = 2 kg, and m3 = 3 kg, connected rigidly by massless rods. The coordinates of the three masses, in m, are (1.25, 3), (2, 2), and (0.75, 0.5), respectively. Find the coordinates of the center of mass of the system

Amother used 150 watts of power to raise a 15 newton object in a time interval of 8.0 seconds. through what vertical distance was the object raised ?

The power exerted by a muscle is the product of the force exerted and the velocity of contraction. the area of which of these shaded regions represents the power exerted while a weight is lifted at maximum speed?
