You are riding a 450-kg horse at 14.4 km h east along a desert road. you have inertia

= 19.32 m/s  and    = 27.32 m/s

Explanation:

The kinetic energy has as formula

        K = ½ m v²

Where m is the mass and v the speed of the body.

If the policeman calculates the kinetic energy, let's clear the speed

       v = √ 2K/m

Let's reduce the units to the SI system

       K = 16.32 KJ (1000 J / kJ) = 16.32 10³ J

Let's calculate

      v = RA (2 16.32 10 3/60)

      v = 23.32 m / s

The rider at 14.4 km/h, reduce

      = 14.4 km / h (1000m / 1km) (1h / 3600s) = 4.00 m / s

We already have the relative speed of the two (rider and police car) which is 23.32, we also have the rider speed 4.0 m / s, let's calculate the possible police speeds

These two speeds come from going in the same direction or in opposite directions

        = ±

         = - vj

         = 23.32 - 4

        = 19.32 m/s

         = + vj

        = 23.32 +4

         = 27.32 m/s

the most accurate qualitative description of the magnetic field vector B inside the cylindrical resistor is "The magnetic field vector points radially away from the axis of the cylinder."

Explanation:

A magnetic field is a vector field that describes the magnetic influence of electric charges in relative motion.
