Sagot :
Cevap:
E Şıkkı
Açıklama:
Ek=1/2.m.V^2
Ek=1/2.2.10^2
Ek= 100J.
Bu enerji, yayi sıkıştıraracagi icin yayin esneklik potansiyel enerjisi esitliginden;
Ep= 1/2k.x^2
100= 1/2.k.(0,2)^2
0,04k=200
k= 5000N/m olur.
Cevap:
Ekin=Eyay
1/2.m.V²=1/2.k.X²
2.10²=k.(2/10)²
200=k.4/100
200.100=4.k
k=20 000/4
k=5000 N/m
