Ini yang lebih jelas kak,tolong bantu jawab….
Jawaban:
1. W = 500 joule
2. P = 2,5 watt
3.
Penjelasan:
nomor 1 :
W = F.s = 200N . 2,5m = 500 joule
Nomor 2 :
P = W/t = 750joule / 300detik = 2,5 watt
Nomor 3 :
W Ani = F.s = 150N . 10m = 1.500 joule
W Ana= F.s = 350N. 40m = 14.000 joule
Selisih = 14.000 joule – 1.500 joule = 12.500 joule
P ani = W / t = 1500joule / 10s = 150 watt
P ana = W/t = 14.000 joule / 10 = 1.400 watt
selisih = 1.400 watt – 150 watt = 1.250 watt
