歡迎來到Yogi老師解題給你看，今天我要講解的是AP Physics C Mechanics的問題
In the figure below, 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 an x axis (on a frictionless floor), where it moves with a constant speed of 10 m/s. Particle 2 of mass m2 = 3 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 during its flight.
(a) What is the maximum height Hmax reached by the center of mass of the two-particle system?
(b) In unit-vector notation, what is the velocity of the center of mass when the center of mass reaches this height? (Express your answer in vector form.)
(c) In unit-vector notation, what is the acceleration of the center of mass when the center of mass reaches this height? (Express your answer in vector form.)
