Jawaban:

m = 8 kg

v = 15 m

k equals 1 half left parenthesis s i l i n d e r space p e j a l right parenthesis

Maka :

E K subscript t r a n s end subscript equals 1 half m v squared E K subscript r o t end subscript equals 1 half I omega squared space equals

Jadi :

E K subscript T o t a l end subscript equals 1 half m v squared left parenthesis K plus 1 right parenthesis

Sehingga :

E K subscript t o t a l end subscript equals 1 half left parenthesis 8 right parenthesis left parenthesis 15 right parenthesis squared open parentheses 1 half plus 1 close parentheses E K subscript t o t a l end subscript space equals space left parenthesis 4 right parenthesis space left parenthesis 225 right parenthesis space open parentheses 3 over 2 close parentheses E K subscript t o t a l end subscript equals 1350 space J
