Fisika Benda bermassa 5 kg bergerak dengan energi kinetik 15 Joule, hitung besar momentum benda tersebut ?​

Benda bermassa 5 kg bergerak dengan energi kinetik 15 Joule, hitung besar momentum benda tersebut ?​

Jawaban:

5 akar 6 N.s

Penjelasan:

Diektahui :

m = 5 kg

EK = 15 J

DItnayakan :

p .. ?

jawab :

EK = p^2/2m

15 = p^2/2x5

15 = p^2/10

p^2 = 15 x 10

p^2 = 150

p = 5 akar 6 N.s

cara lain

mencari massa benda

EK = 1/2 m v^2

15 = 1/2 5 v^2

15 x 2/5 = v^2

6 = v^2

v = akar 6 m/s

mencari momentum benda

p = mv

p = 5 akar 6 N.s
