A 65 kg person is in a head-on collision. The car's speed at impact is 17 m/s . Estimate the net force on the person if he or she is wearing a seat belt and if the air bag deploys. Express your answer to two significant figures and include the appropriate units.

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm).
