A) \[\frac{1}{3}\,m/{{s}^{2}}\]
B) \[\frac{1}{4}m/{{s}^{2}}\]
C) \[\frac{1}{5}\,m/{{s}^{2}}\]
D) \[\frac{1}{6}\,m/{{s}^{2}}\]
Correct Answer: C
Solution :
Force produced by the engine\[F=\frac{P}{v}\,=\,\frac{30\times {{10}^{3}}}{30}\]=103N Acceleration=\[\frac{\text{Forward force by engine--resistive force}}{\text{mass of car}}\] \[=\frac{1000-750}{1250}=\frac{250}{1250}\]=\[\frac{1}{5}m/{{s}^{2}}\]
