Answer:
205N
Explanation:
The net force (F) is the difference between the applied force([tex]F_{A}[/tex]) and the kinetic frictional force([tex]F_{R}[/tex]). i.e
F = [tex]F_{A}[/tex] - [tex]F_{R}[/tex] -----------------(i)
Note that;
[tex]F_{R}[/tex] = μmg
Where;
μ = coefficient of kinetic friction
m = mass of the body
g = acceleration due to gravity = 10m/s²
Equation (i) then becomes;
F = [tex]F_{A}[/tex] - μmg -------------------(ii)
Given from question;
m = mass of motorcycle = 150kg
μ = 0.03
[tex]F_{A}[/tex] = 250N
Substitute these values into equation (ii) as follows;
F = 250 - (0.03 x 150 x 10)
F = 250 - (45)
F = 205N
Therefore, the net force applied to the motorcycle is 205N
