An object with mass m1 = 3.00 kg is moving along the positive x axis with a speed v1i = 2 m/s straight towards two objects with masses m2 = 2.00 kg and m3 = 4.00 kg, which are initially at rest. When they collide, object 1 comes to rest and object 2 moves away with a speed of v2f = 1.5 m/s at an angle of 50 degrees above the x axis. What is the direction of the velocity of the center of mass of the system comprised of all three objects after the collision?
A) Along the x axis
B) A an angle of 50 degrees above the x axis
C) At an angle of 50 degrees below the x axis
D) At an angle > 0 degrees and <50 degrees above the x axis
E) At an angle>0 degrees and <50 degrees below the x axis
The correct answer is A but I am confused why it is A, if you could explain the justification as to why the answer is option A.
Consider a system consisting of three objects: Object A with a mass of 2 kg located at position (1, 0), Object B with a mass of 3 kg located
at position (0, 2), and Object C with a mass of 1 kg located at position (-2, -1). What is the center of mass of this system?
Three particles of masses m1 = 2.5 kg, m2 = 4.1 kg and m3 = 3.1kg are atthe corners of an equilateral triangle of side 100 cm. If the particle m1 is located at theorigin Find the center of mass of the whole system. and Write the position of the center in unit-vector notation.
