Answer: 10 s
Explanation:
Given
Engine generates [tex]100,000\ W[/tex] power
Force exerts [tex]F=10,000\ N[/tex]
Distance traveled [tex]d=100\ m[/tex]
work done is given by
[tex]W=F\cdot d\\W=10,000\times 100\\W=10^5\ J[/tex]
Also, Energy is given as
[tex]\Rightarrow E=P\cdot t[/tex]
Insert the values
[tex]\Rightarrow 10^6=100,000\times t\\\\\Rightarrow t=\dfrac{10^6}{10^5}\\\\\Rightarrow t=10\ s[/tex]
