Answer:
The energy dissipated is [tex]E = 9.8 J[/tex]
Explanation:
From the question we are told that
The distance covered at constant velocity d = 2 m
The velocity is [tex]v = 1.5 \ m/s[/tex]
Generally at constant velocity the magnetic force on the bar is mathematically represented as
[tex]F = m * g[/tex]
substituting values
[tex]F = 0.5 * 9.8[/tex]
[tex]F = 4.9 \ N[/tex]
The energy dissipated is mathematically evaluate as
[tex]E = F * d[/tex]
substituting the value
[tex]E = 4.9 * 2[/tex]
[tex]E = 9.8 J[/tex]
