A 40 kg ball is located at x 40m y 0m a 60 kg ball is, Ask an Expert

Academics

A 4.0 kg ball is located at x= 4.0m, y= 0m. A 6.0 kg ball is located at x= 2.0m, y= 4.0m, and a 3.0 kg ball s located at x= -1.0m, y= -2.0m.

a. What is the location of the center of the mass of this system?

b. If the 4.0 kg ball is moving in the positive x-direction at 5.0 m/s, the 6.0 kg ball is moving in the positive y-direction at 8.0 m/s, and the 3.0 kg ball is moving in the negative x-direction at 3.0 m/s, what are the x and y components of the velocity of the center of mass of the three balls?
