Problem
Two ice-skaters start from the same point on a frictionless rink. Skater A of mass 60kg glides eastwards at 3ms−1 while skater B of mass 45kg moves southwards at 4ms−1. (i) Compute the linear momentum vector of each skater. (ii) Determine the magnitude of the total linear momentum of the two-skater system.
(i) Linear momentum of skater A and skater B
(ii) Magnitude of total momentum
