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 13.0 m/s. Particle 2 of mass m2 = 3.60 g is shot with a velocity of magnitude 26.0 m/s, at an upward angle such that it always stays directly above particle 1 during its flight.
(b) What is the magnitude and direction of the velocity of the center of mass when the center of mass reaches this height?
m/s?
degrees counter clockwise from positive x
(c) What is the magnitude and direction of the acceleration of the center of mass when the center of mass reaches this height?
m/s^2?
degrees counter clockwise from positive x?
