Coba uraikan perhitungan berikut :
F x At = m(v2-v1)
F x 0,001 s = 0, 2 kg (30-(-20))
F x (1/1000) = (2/10) x (50)
F = 10.000 N
Kok bisa jadi 10.000 N?
F x At = m(v2-v1)
F x 0,001 s = 0, 2 kg (30-(-20))
F x (1/1000) = (2/10) x (50)
F = 10.000 N
Kok bisa jadi 10.000 N?
Δt=0,001s=1×10⁻³s
m=0,2 kg
v₂=30
v₁=-20 (-karena arahnya berlawanan sama v₂)
I=I
F×Δt=Δp
F×Δt=m(v₂-v₁)
F×1×10⁻³=0,2(30-(-20)
1×10⁻³F= 0,2(50)
1×10⁻³F= 10
F=
F=10⁴
F=10000 N
