Pembahasan Soal:

F equals m. a space space space equals kg space bevelled straight m over straight s squared space space equals open square brackets straight M close square brackets open square brackets straight L close square brackets open square brackets straight T close square brackets to the power of negative 2 end exponent 

satuan k g space m divided by s squared space equals space N

Pernyataan (1)  Satuan benar, Dimensi salah

 

W equals F. s space space space space equals bevelled fraction numerator kg space straight m squared over denominator straight s squared end fraction space space space space equals open square brackets straight M close square brackets open square brackets straight L close square brackets squared open square brackets straight T close square brackets to the power of negative 2 end exponent 

satuan k g space bevelled m squared over s squared space equals space J

Pernyataan (2) Satuan benar, Dimensi salah

 

p equals m v space space space equals kg space bevelled straight m over straight s space space space space equals open square brackets straight M close square brackets open square brackets straight L close square brackets open square brackets straight T close square brackets to the power of negative 1 end exponent 

satuan k g space bevelled m over s space equals N. s

Pernyataan (3) Satuan benar, Dimensi benar

 

P equals F over A space space space space equals bevelled kg over ms squared space space space space equals open square brackets straight M close square brackets open square brackets straight L close square brackets to the power of negative 1 end exponent open square brackets straight T close square brackets to the power of negative 2 end exponent 

satuan bevelled fraction numerator k g over denominator m s squared end fraction space equals space bevelled N over m squared

Pernyataan (4) Satuan benar, Dimensi salah

 

P equals W over t space space space equals kg bevelled straight m squared over straight s cubed space space space equals open square brackets straight M close square brackets open square brackets straight L close square brackets squared open square brackets straight T close square brackets to the power of negative 3 end exponent 

satuan kg bevelled straight m squared over straight s cubed space equals space bevelled J over s

Pernyataan (5) Satuan benar, Dimensi benar

Jadi, jawaban yang tepat adalah nomor 3 dan 5 (C)
