C. R = \frac{Vo ^{2} sin  \alpha }{g} = \frac{4 ^{2} sin  60^{0}  }{10} = \frac{1600  \frac{1}{2} \sqrt{3}  }{10} =  \frac{800 \sqrt{3} }{10} = 80 \sqrt{3}
B. TH=  \frac{Vo sin  \alpha }{g} = \frac{40 sin 60^{0} }{10} = \frac{40  \frac{1}{2}  \sqrt{3} }{10} = \frac{20  \sqrt{3} }{10} = 2 \sqrt{3}



itu satuannya apa yah?
c. meter (m)
b. sekon (s)
