tlong jawabkan no 1-3 masih bingung sama rumus tlong bantuannya

No. 1
-------
Diket :
Usaha, W = 750 J
Waktu, t = 5 menit = 5 x 60 sec = 300 sec

Tanya :
Daya, P = __?

Jawab :
P = W/t
P = 750/300
P = 2,5 watt

No. 2
--------
Diket :
Gaya, F = 100 N
Jarak perpindahan, s = 4 meter
Waktu, t = 20 sec

Tanya :
Daya, P = __?

Jawab :
Step 1
---------
Cari dulu usaha nya yak
W = F.s
W = 100•4
W = 400 Joule

Step 2
---------
Daya,
P = W/t
P = 400/20
P = 20 watt

No. 3
--------
Diket :
Gaya, F = 5 N
Kecepatan, v = 2 m/s

Tanya :
Daya, P = __?

Jawab :

P = W/t
P = F.s/t
Krn V = s/t
Maka :
P = F.V
P = 5•2
P = 10 watt
