A horse shoe magnet is placed on a mass balance such that a uniform magnetic field of magnitude B runs between it from North to
South. A coil of resistance R is connected to a battery which supplies a potential difference of V across the coil and is suspended such that a section of the coil of length L meters lies between it with current running from East to West. The mass balance measures a mass of M.
1. What is the measured change in mass due to the effect of Fmag?
2. What is the total measured mass of the magnets? Keep in mind the effect of Newton's third law.

The answer for your problem is shown on the picture.
Answer:
Coefficient of friction will be 0.587
Explanation:
We have given mass of the car m = 500 kg
Distance s = 18.25 m
Initial velocity of the car u = 14.5 m/sec
As the car finally stops so final velocity v = 0 m/sec
From second equation of motion
We know that acceleration is given by
So coefficient of friction will be 0.587
