pleasee helpp!!! and if you know the following it would also help
a high-jumper lands on a mat.....what is the reaction
and an airplane's jet engine pushes air toward the back of the airplane....what is the reaction
the reaction of the boat is equal to the mass of the anchor and its acceleration
the reaction of the mat of the jumper=the mass of the jumper x acceleration due to gravity(9.8m/s^-2)
the reaction of the air is equal but opposite to the force (Ma) provided by the jet engine)
