Coefficient of friction*weight.
= 63500*0.018 = 1143.
= 63500*0.018 = 1143.

Simple formula.
Rr = Kr * W.
Where, Rr = Rolling Resistance (N)
Kr = Coefficient of Rolling Resistance.
W = Weight of the Vehicle (N).
So here,
W = 63500 N.
Kr = 0.018.
Rr=?
Put value in equation.
Rr = Kr * W.
= 0.018 *63 500.
Rr = 1143 N ==> Answer.
Rr = Kr * W.
Where, Rr = Rolling Resistance (N)
Kr = Coefficient of Rolling Resistance.
W = Weight of the Vehicle (N).
So here,
W = 63500 N.
Kr = 0.018.
Rr=?
Put value in equation.
Rr = Kr * W.
= 0.018 *63 500.
Rr = 1143 N ==> Answer.
