Fx = 20 cos 50º Fx = 20 sin (40º)
= 12,86 N = 12,86 N
(3)
2.4 Fx(net) = Fx(20N) + Fx(25N) – Fx(P)
15,49 = 12,86 + 25 cos 30º - Fx(P)
Fx(P) = 19,02 N
Cos 20 = 19,02 /F
F = 20,24 N (6)
2.5 Option 1/Opsie 1 Option 2/Opsie 2
Fy(p) = F sin θ Fy(p) = F cos θ

QUESTION 3/VRAAG 3
3.1 The rate of change of velocity of an object. (2)
Die tempo van verandering in snelheid van ‘n voorwerp.

QUESTION 4/ VRAAG 4
4.1 When object/body A exerts a force on object/body B, object/body B will exert
the same force on object/body A simultaneously in the opposite direction.
Wanneer voorwerp A 'n krag op voorwerp B uitoefen, oefen voorwerp B
GELYKTYDIG 'n krag van gelyke grootte in die teenoorgestelde rigting op
voorwerp A uit. (2)
4.2
(4)
4.3 Fnet = ma
Block/Blok A Block/Blok B
Fg = mg Fg// - T - fk = ma/mg sin θ – T – fk = ma
19,6 = m x 9.8 18 x 9,8 sin 35º - T – 20 = 18a
m = 2 kg T = 81,18 -18a …(2)
T - Fg = ma
T – 19,6 = 2a
T = 2a + 19,6 …(1)
2a + 19,6 = 81,18 -18a
20a = 81,58
a = 3,08 m.s-2 (7)
4.4 Option 1/Opsie 1 Option 2/Opsie 2
T = 81,18 -18(3,08) T = 2(3,08) + 19,6
