Penjelasan:

1. Ep = m.g.h

= 2,5.10.0,8

= 20 joule

2. Ep = ½.k.x.2

= ½(150)(0,2)2

= ½(60

= 30 Joule

3. W = ½.k.(∆x)²

= ½(50)(0,04)²

= ½.4

= 2 Joule

4. Ek = 0,5.m.v²

= 0,5(1.200)(50)²

= 1.500.000 Joule

5. W = ½.m.(v2 – v1)2

= ½(1.200)(40-20)2

= ½(1.200)(20)2

= 24.000 Joule

Maaf kalau salah
