![47. A war-wolf or trebuchet is a device used during the Mid-
dle 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 Figure P10.47. Model it
as a stiff rod of negligible mass, 3.00 m long, joining
particles of mass m, = 0.120 kg and m2 = 60.0 kg at its

small-mass object is gaining speed, does it move with
constant acceleration? (c) Does it move with constant
tangential acceleration? (d) Does the trebuchet move
with constant angular acceleration? (e) Does it have
