Question
**22. Three children are standing together on a totally frictionless pond. At the count of
three, they all push against each other in an attempt to escape to the edge of the pond. Child 1
(m1 = 50 kg) ends up moving north at 4 m/s. Child 2 (m2 30 kg) ends up moving east at
5 m/s. Child 3 has mass m3 50 kg and ends up moving at an angle 0 south of west, as shown.
a) Is the magnitude of the impulse experienced by Child l as they push off greater than,
equal to, or less than the magnitude of the impulse experienced by Child 2 as they push
off? Explain.
m,= 50 kg
e=?
m3= 50
V3=?
b) Find the final velocity of Child 3 (magnitude and direction).
