The driver of a 1000 kg car traveling on a highway at 35 m-s'applies brake to avoid hitting a van in front of him, which had come to rest because of trans ahead. After the brakes are applied, a constant frictional force of 8000 N on the car car 35 m- 1,8 1000kg BOOON 52.1 State the WORK- ENERGY THEOREM in words 22 Using ENERGY PRINCIPLES, determine the minimum distance requi for the brakes of the car to be applied to avoid a collision with the van? ​

The earth's magnetic field, with a magnetic dipole moment of 8.0×1022am2, is generated by currents within the molten iron of the earth's outer core. suppose we model the core current as a 3000-km-diameter current loop made from a 1000-km-diameter “wire.” the loop diameter is measured from the centers of this very fat wire. to decide whether this is a large or a small current density, compare it to the current density of a 7.0 a current in a 2.0-mm-diameter wire.
