Q. 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. Model it as a stiff rod of negligible mass, 2.60 m long, joining particles of mass 59.5 kg and 0.110 kg at its ends. It can turn on a frictionless, horizontal axle perpendicular to the rod and 14.0 cm from the large-mass particle. The rod is released from rest in a horizontal orientation.
(a) Find the maximum speed that the 0.110 kg object attains. m/s
(b) Select the statements that are true.
While the smaller object is gaining speed, it moves with constant acceleration.
The smaller object does not move with constant tangential acceleration.
The trebuchet moves with constant angular acceleration.
The trebuchet maintains constant momentum.
The trebuchet-Earth system has constant mechanical energy.
