Question

Please yg no 5 dng caranya

Answer 1

A = (mB x g) / (mA + Mb)
a = (10 x 10) / (30 + 10)
a = 100/40 = 2.5 m/s^2

Asal usul rumusnya dari,
Persamaan pertama: T = mA x a
Persamaan kedua : W - T = mB x a
Tinggal disubstitusi T nya, jadi deh.
a = mB x g/(mA + mB)

Answer 2

a = (mB x g) / (mA + Mb)
a = (10 x 10) / (30 + 10)
a = 100/40 = 2.5 m/s^2
