1. Ez= m⋅g⋅h
Ez= 2,0 ⋅ 9,81 ⋅ 5,0
Ez= 98,1 J
2. Ez= m⋅g⋅h
Ez= 10,0 ⋅ 9,81 ⋅ 8,0
Ez= 784,8 J
3. m= Ez : (g⋅h)
m= 147 : (9,81 ⋅ 3,0)
m= 5,0 kg
4. h= Ez : (m ⋅ g)
h= 8820 : (60,0 ⋅ 9,81)
h= 15,0 m
5. h= Ez : (m ⋅ g)
h= 2940 : (15,0⋅9,81)
h= 20,0 m
6. h= Ez : (m ⋅ g)
h= 980 : (25,0 ⋅ 9,81)
h= 4,0 m
7. Ez= m ⋅ g ⋅ h
Ez= 500,0 ⋅ 9,81 ⋅ 20,0
Ez= 98100 J
8. m= Ez : (g ⋅ h)
m= 58800 : (9,81 ⋅ 12,0)
m= 500,0 kg
9. h= Ez : (m ⋅ g)
h= 176400 : (300,0 ⋅ 9,81)
h= 60,0 m
10. m= Ez : (g ⋅ h)
m= 3000 : (9,81 ⋅ 15,0)
m= 20,4 kg
