A war-wolf or trebuchet is a device used during the Middle Ages to throw rocks at castles and now sometimes used to fling large vegetables and pianos as a sport. A simple trebuchet is shown in the figure below. Model it as a stiff rod of negligible mass, d = 2.80 m long, joining particles of mass m1 = 0.115 kg and m2 = 72.5 kg at its ends. It can turn on a frictionless, horizontal axle perpendicular to the rod and 13.0 cm from the large-mass particle. The operator releases the trebuchet from rest in a horizontal orientation. A simple trebuchet is shown. It can be modeled as a rod of length d with the centers of two masses, m1 and m2, at the left and right ends of the rod, respectively. Mass m1 is smaller than mass m2. The pivot of the trebuchet is to the right of the center of the rod, closer to m2. A man holds m2 such that the rod rests in a horizontal position. (a) Find the maximum speed that the small-mass object attains when it leaves the trebuchet horizontally

Question

war-wolf or trebuchet is a device used during the Middle Ages to throw rocks at castles and now sometimes used to fling large vegetables and pianos as a sport. A simple trebuchet is shown in the figure below. Model it as a stiff rod of negligible mass, d = 2.80 m long, joining particles of mass m1 = 0.115 kg and m2 = 72.5 kg at its ends. It can turn on a frictionless, horizontal axle perpendicular to the rod and 13.0 cm from the large-mass particle. The operator releases the trebuchet from rest in a horizontal orientation.
