Answer:
0.06 A
Explanation:
We have given mass =0.954 kg
velocity =1.27 m/sec
efficiency =0.361 the output kinetic energy of the motor 
Efficiency =0.361
so input to the motor = output/efficiency
so input to the motor = 
we know that 
where E is energy and T is time so 
We know that power P=VI we have given V=4.5 VOLT
So current
