E and f only please!

A man of mass m1 = 70.0 kg is skating at V1 = 8.00 m/s behind his wife of
mass m2 = 50.0 kg, who is skating at v2 = 4.00 m/s. Instead of passing her,
he inadvertently collides with her. He grabs her around the waist, and they
maintain their balance.
(a) Sketch the problem with before-and-after diagrams, representing
the skaters as blocks. (Do this on paper. Your instructor may ask you to
turn in this work.)
(b) Is the collision best described as elastic, inelastic, or perfectly
inelastic?
O elastic
O inelastic
O perfectly inelastic
(c) Why?
They have the same velocity after collision.
This answer has not been graded yet.
(d) Write the general equation for conservation of momentum in terms
of m1, V1, m2, V2, and final velocity vf. (Do this on paper. Your
instructor may ask you to turn in this work.)
(e) Solve the momentum equation for vf. (Use the following as
necessary: m1, V1, m2, v2. Do not substitute numerical values; use
variables only.)
Vr=
(f) Substitute values, obtaining the numerical value for vf, their speed
after the collision.
Vr, couple
m/s
Vr, man -
m/s
Vr, wife
m/s
