Magnitude and direction of the velocity of center of mass

Reference no: EM13542442

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?

Assuming no friction between the boat and the wate : In figure (a), a 4.2 kg dog stands on a 15 kg flatboat at distance D = 6.1 m from the shore. It walks 2.1 m along the boat toward shore and then stops. Assuming no friction between the boat and the water, find how far the dog is then from the shore.
