A person standing on a frictionless horizontal surface throws a ball due east with a force of FPB=12i^−9j^N, where i^ points east and j^ points vertically upward.
a. (i) Determine, in unit–vector form, the force exerted by the ball on the person.
b. (ii) Calculate the magnitude of each force.
c. (iii) Verify numerically that the two forces satisfy the vector form of Newton’s third law.
