kinetisk energi

Opg 1
LaTex: E_{kin} = \frac{1}{2}\cdot 950 \cdot \frac{100}{3.6}^2 = 366512.346
Opg 2
LaTex: v = \sqrt{\frac{5000\cdot 2}{80}}\cdot 3.6=40,25 km/t
Opg 3
LaTex: E_{pot} = 9,82\cdot 80\cdot 35 = 27,496 kJ\\v=\sqrt{\frac{E_{pot}}{\frac{1}{2}\cdot 80}} = 26.22 \frac{m}{s}
Opg 4
LaTex: h = h\cdot (1-0.13) = 3,48 m
Opg 5
LaTex: h=\frac{\left(\frac{80}{3,6}\right)^2\cdot 0,5}{g} = 246,9 m
