A 30kg girl moving with speed 2m/sec and a 50kg boy moving with speed 1m/sec collide head-on on an ice-skating rink. As a result of the collision, the girl moves at 1m/sec opposite to her initial direction. Find the magnitude and direction of the boy's velocity after the collision.© BrainMass Inc. brainmass.com November 24, 2022, 11:35 am ad1c9bdddf
We know from momentum equation
m1u1 +m2u2 =m1v1+m2v2
taking m1 ...
The solution clearly explains the problem and calculates the answer. The magnitude and direction of boy's velocity after collision are calculated. An ice-skating rink collision is determined.
