Keyon Fletcher · Answer 1

Jayme = >m1 = 40 kg, v1 = 4 m/s, North

Antony = >m2 = 65 kg, v2 = 12 m/s South

Jayme + Antony = > mf = 105 kg, vf = ?

This is a question of conservation of momentum. Therefore;

m1v1 + m2v2 = mfvf

Substituting;

40*4 + 65*12 = 105*vf

160 + 780 = 105vf

940 = 105vf

vf = 940/105 = 8.95 m/s

The velocity of Jayme and Antony skating together will be 8.95 m/s.
