Duuuużo pkt !!!!!!!!!! zadania: 2.14 2.15 2.16

[latex]Zad 2.14\ g=10frac{m}{s^2}\ t_c=10s\ t_1=5s\\ H=frac{gt_c^2}{2}=frac{10*10^2}{2}=500m\\ Delta h=frac{gt_1^2}{2}=frac{10*5^2}{2}=125m\\ h_{5s}=H-Delta h=500-125=375m[/latex] [latex]Zad 2.15.\ H=360mRightarrow Delta h=h_2=frac{H}{2}=180m\ g=10frac{m}{s^2}\\ Delta h=frac{gt^2}{2}Rightarrow t=sqrt{frac{2Delta h}{g}}\\ t=sqrt{frac{2*180}{10}}=6s[/latex] [latex]Zad 2.16.\ t=5s\ g=10frac{m}{s^2}\\ s_A=frac{gt^2}{2}=frac{10*5^2}{2}=125m\\ s_B=v_0t+frac{gt^2}{2}=2*5+125=10+125=135\\ Delta s=s_B-s_A=125-135=10m[/latex] Pozdrawiam, Adam
