Penyelesaian: diket: m = 10kg, s= 5m, g= 9,8m/s2. sudut=37 drajat dit : v = ? jwb: rms: v= akar 2.g.h h blm diketahui. untk cari h, pake rms: sin 37 drajat = sin 37 = h/5 (sin 37 = 0,618) 0,6018 = h/5 h = 0,6018 x 5 = 3,009 maka v= akar 2.g.h = akar 2 x 9,8 x 3,009 = akar 58, 9764 = 7,679 = 7,68 m/s
dit : v = ?
jwb: rms: v= akar 2.g.h
h blm diketahui. untk cari h, pake rms: sin 37 drajat
= sin 37 = h/5 (sin 37 = 0,618)
0,6018 = h/5
h = 0,6018 x 5 = 3,009
maka v= akar 2.g.h
= akar 2 x 9,8 x 3,009 = akar 58, 9764 = 7,679 = 7,68 m/s
