bestie jawabnya no ngasal,pliss, soalnya ini butuhnya sekarang ......,jawab y pliss,i love you , makasih...
4. Ek = 1/2 m.v^2
18 J= 1/2 m (3)^2
18 J= 1/2 m.9
18.2/9=m
m= 4kg
5. Ek = 1/2 m.v^2
8.82= 1/2 . 4 . v^2
8.82= 2 . v^2
v= √4,41 = 2.1 m/s
6. Ep= m.g.h
Ep= 2.5*10*15
Ep= 375 J
7. Ep= m.g.h
240= m . 10 . 12
240= m . 120
m= 2kg
