Công thức: \(A=P\cdot t=F\cdot s\Rightarrow s=\dfrac{P\cdot t}{F}\)
1.\(s_1=\dfrac{P_1\cdot t_1}{F_1}=\dfrac{25\cdot12}{5}=60m\)
2.\(F_2=\dfrac{P_2\cdot t_2}{s_2}=\dfrac{800\cdot50}{0,3}=133333,33N\)
3.\(s_3=\dfrac{P_3\cdot t_3}{F_3}=\dfrac{250\cdot3,5\cdot60}{50}=1050m\)
4.\(s_4=\dfrac{P_4\cdot t_4}{F_4}=\dfrac{196\cdot\dfrac{1}{3}\cdot3600}{2,2}=106909m\)
