Explanation / Answer

5)

let m1 = 79 kg, m2 = 42 kg

v = 8.4 m/s

v2 = 10.1 m/s
v1 = ?

Apply conservation of momentm

final momentum = initial momentum

m1*v1 + m2*v2 = (m1+m2)*v

m1*v1 = (m1 + m2)*v - m2*v2

v1 = ( (m1 + m2)*v - m2*v2)/m1

= ( (79 + 42)*8.4 - 42*10.1)/79

= 7.50 m/s <<<<<------------------------Answer

6)

let v is the speed of Gudesi towards west.

so,
58*v = 43*6.5

v = 43*6.5/58

= 4.82 m/s

separtion after 4.5 s = 1.2 + (4.82 + 6.5)*4.5

= 52 m
