Two 0.1 kg-masses

1. Two 0.1 kg-masses are connected to a linear spring on a frictionless table. The center of mass of the 2- particle system is stationary. At the instant shown, the velocity is v'1 = v'2 = 0.1e“r + 2‘5e“9 refs and
r=D.5 m. The spring constant, K=10 Mum and the spring applies no force when the masses are at the origin, so Fm2Kr. 3. Determine the maximum and minimum distanms to the origin [rmin and rmax} b. Determine the speed at these points, |u| , when r= rmin and when r = rmax F=2kr F=2k ”IV Figure 1: Two masses mnmtnd by a Spring 4. Two masses are connected by a 0.4wm-rnassiess cord. Mass B is released when mass A is 1350 from
the horizontal axis and rotating at w=-23.57 radls. There is a wall 10 m away from the center of mass. G.
when the system was released. Mass A is £34125 kg and mass B is 0.375 kg. 3. What is the angle of the card when the center of mass is at its maximum height? h. Which mass will impact the wall first?
