(3 marks) b Two ice skaters are practising a lift. They skate directly towards each other.
The woman has a mass of 60 kg and a velocity of 3 m/s towards the east.
The man has a mass of 100 kg and is skating at a velocity of 4 m/s towards
the west. They time it badly and collide and bounce off each other's
outstretched hands. The woman moves off at a velocity of 5 m/s towards the
west. With what velocity does the man move off and in which direction?

plz help ​

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
