A 5 cm length of wire carries a current of 3 A in the positive z direction. The force on this wire due to a magnetic field vector is vector = (-0.2 ihatbold + 0.2 jhatbold) N.

For an object starting from rest and accelerating with constant acceleration, distance traveled is proportional to the square of the time. if an object travels 2.0 furlongs in the first 2.0 s, how far will it travel in the first 4.0 s?
