A 0.954-kg toy car is powered by three D cells (4.50 V total) connected directly to a small DC motor. The car has an effective e
Natasha2012 [34]

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 KE=\frac{1}{2}mv^2=\frac{1}{2}\times 0.954\times 1.27^2=0.769\ J

Efficiency =0.361

so input to the motor = output/efficiency

so input to the motor = \frac{0.769}{0.361}=2.1301

we know that P=\frac{E}{T} where E is energy and T is time so P=\frac{2.1301}{7.88}=0.2703W

We know that power P=VI we have given V=4.5 VOLT

So current I=\frac{P}{V}=\frac{0.2703}{4.5}=0.06 A
