Answer only Number 7

6 A 70kg fisherman is fishing in a 40kg dinghy at rest
on a still lake when, suddenly, he is attacked by a
swarm of wasps. To escape, he leaps into the water
and exerts a horizontal force of 140N north on the
boat.
a What force does the boat exert on the fisherman?
b With what acceleration will the boat move initially?
c If the force on the fisherman lasted for 0.50 s,
determine the initial speed attained by both the
man and the boat.
7 An astronaut becomes untethered during a space-walk
and drifts away from the spacecraft. To get back to the
ship, she decides to throw her tool kit away. In which
direction should she throw the tool kit?
