Question
The figure shows the positions and velocities of two particles. If the particles move under the mutual attraction of each other, then the position of centre of mass at t = 1 s is
Options
A.x = 5m
B.x = 6m
C.x = 3m
D.x = 2m
Solution
vCM = 
= 1m/s
Position of centre of mass at t = 1s
XCM =
+ (1)(1) = 5 + 1 = 6m
= 1m/sPosition of centre of mass at t = 1s
XCM =
+ (1)(1) = 5 + 1 = 6mCreate a free account to view solution
