Jawaban:
15 meter diatas permukaan tanah
Penjelasan:
Waktu saat bola bertemu
[tex] \rm t=\frac{h}{v_{0A}+v_{0B}}[/tex]
[tex]\rm t=\frac{60}{0+20}=3\:s[/tex]
Ketinggian Bola B saat bertemu
[tex]\rm h_B=v_{0B}t-\frac{1}{2}gt^2[/tex]
[tex]\rm h_B=20(3)-\frac{1}{2}(10)(3)^2[/tex]
[tex]\rm h_B=60-5(9)=60-45[/tex]
[tex]\rm h_B=15\: m[/tex]
