...A man of mass 80kg is in a balloon basket of mass 40kg. The man is holding a bag of ballast of mass 60kg.
the basket with its contents attached to a balloon are accelerating downwards at 2.8m/sec^2
a) what is the force exerted by the man on the bag of ballast?
b) what forces are exerted on the man by
i) the bag of ballast? equal and opposite to the force exerted by the man on the ballast (3rd law, right?)
ii) the basket? basket pushes up on the man ... what other force acts on the man? ... net force on the man?
a) 60g- R = 60x2.8 ( where R is the force exerted by the man on the bag)
i) 60g= 588N ( force exerted by the bag on the man)
ii) (420+ 80g) - B = 80x2.8 ( where B is the force of the basket on the man)
question , is part I and ii correct not sure
