Question

A 60 kg football player running at 8 m/s collides with a 50 kg football player running -6 m/s. What will be the speed of the tangled players in m/s?

Answer 1

50 kg football player: 9.272727272727273

60 kg football player: -4.7272727272727275

Explanation (formula):

m1·vi1 + m2·vi2 = m1·vf1 + m2·vf2

vf1 = [(m1 – m2)·vI1 + 2 m2·vI2]/(m1 + m2)

vf2 = [2 m1·vI1 – (m1 – m2)·vI2]/(m1 + m2)
