In the figure, two particles are launched from the origin of the coordinate system at time t 0. Particle 1 of mass m¡ = 4.90 g is shot directly along the x axis (on a frictionless floor), where it moves with a constant speed of 12.3 m/s. Particle 2 of mass m2 = 2.50 g is shot with a velocity of magnitude 15.3 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?

Question
In the figure, two particles are launched from the origin of the coordinate system at time t = 0. Particle 1 of mass m¡ = 4.90g is shot
directly along the x axis (on a frictionless floor), where it moves with a constant speed of 12.3 m/s. Particle 2 of mass m2 = 2.50 g is shot
with a velocity of magnitude 15.3 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?
