Answer:
Explanation:
To calculate the force we need to use this equation
where L is the total length of the wire
So in this case the small element of current is
Because x is the direction of the current flow.
As is said in the problem B is such that
so to use the equation above we first calculate the following cross product:
so the force:
So here we use the fact that B=0 in any point of the x axis that is not , that means that we only need to do the integration between a very short distant behind the point and a very short distant after that point, meaning:
so is the same as evaluating at
that is:

Answer:
Distance = 13.9 meters
Explanation:
Given the following data;
Maximum speed = 150 km/hr to meters per seconds = 150 * 1000/3600 = 41.67 m/s
Decelerating speed = 3m/s
To find the distance travelled with this speed;
Distance = maximum speed/decelerating speed
Distance = 41.67/3
Distance = 13.9 meters
Therefore, the bus would travel a distance of 13.9 meters before stopping.
