In the figure, two particles are launched from the origin of the
coordinate system at time t = 0. Particle 1 of mass
m1 = 5.80 g is shot directly along the
x axis (on a frictionless floor), where it moves with a
constant speed of 10.7 m/s. Particle 2 of mass
m2 = 1.80 g is shot with a velocity of
magnitude 25.0 m/s, at an upward angle such that it always stays
directly above particle 1 during its flight. (a)
What is the maximum height Hmax reached by the
com of the two-particle system? In unit-vector notation, what are
the (b) velocity and (c)
acceleration of the com when the com reaches
Hmax?
