Menjawab:
a) 250N
b) 250Watt
Penjelasan:
a) Upaya yang dilakukan beny untuk mendorong gerobak tersebut setara dengan gaya yang diterapkan untuk mendorong beban. Oleh karena itu, Effort beny yang digunakan setara dengan 250N
b) Daya = Pekerjaan selesai / Waktu
Karena usaha yang dilakukan = Gaya × jarak
Daya = Gaya × jarak / waktu
Diberikan
Angkatan = 250N
Jarak = 50m
Waktu = 50 detik
Yg dibutuhkan
Power Beny melakukannya untuk mendorong keranjang belanjaan.
Daya = 250 × 50/50
Daya = 12500/50
Daya = 250Watt
Oleh karena itu, Benny menggunakan tenaga 250 watt untuk mendorong kereta belanja tersebut
