In Figure 9-43, two particles are launched from the origin
Chapter , Problem 14(choose chapter or problem)
In Figure 9-43, two particles are launched from the origin of the coordinate system at time t ! 0. Particle 1 of mass m1 ! 5.00 g is shot directly along the x axis on a frictionless floor, with constant speed 10.0 m/s. Particle 2 of mass m2 ! 3.00 g is shot with a velocity of magnitude 20.0 m/s, at an upward angle such that it always stays directly above particle 1. (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?

Step By Step Solution
Step 1 of 6
Two particles launched, 1along x axis, and 2 with an angle upwards. It is obvious that particle 1 has only horizontal components of velocity and particle 2 has both vertical and horizontal components.
Horizontal initial components of velocities of both the particles are same,
