Tolong Dijawab ya semuanya dengan caranya NO = 5 6 7 8 9 dikumpul besok pleaseeee

Answer 1

Verified answer

5.) dik : F = 30N dan S= 16m
dit : W

jawab : 30N x 16m = 480 J

6.) W=F.s
= 96.6
= 576 J
W = ∆Ek
576 = 1/2.32.V
576 =16.V
V = 576/16
v = 36 m/s

7.) vt = vo - gt
0 = 10 - 10 t
10t = 10
t = 1s

s = vo t - 1/2 gt²
s = 10 (1) 1/2 (10) 1²
s = 10 - 5
s = 5 m

W = F s
W = m g s
W = 0,5 10 5
W = 25 J

8.) W = ΔEp = m.g.Δh
= 20 . 9,8 . 0.1 cm = 19,6
P = ΔEp/t = 19,6/1 = 19,6 J/s

9.) W = F .s
W =ΔEk
W = 1/2 mv^2
= 1/2 m (3^2 - 1,4^2)
= 1/2 m (9 - 1,96)
= 1/2 m (7,04)
= 3,52 m Joule
