3.1.2 The force that opposes the tendency of motion of a stationary object relative
to a surface. Die krag wat te bowe gekom word om ‘n stilstaande voorwerp
te laat beweeg. 

3.1.3 Ff = mg sin θ (3)

Ff = 95.0 × 9.8 × sin 23.2° 
Ff = 366.76 N 
3.1.4 N = mg cos θ (3)
N = 95.0 × 9.8 × cos 23.2° 
N = 855.72 N 
3.1.5 𝑓𝑠 = 𝜇𝑠 𝑁 √
366,76 = 𝜇 𝑆 x 855,72 √

𝜇𝑠 = 0,43 √

QUESTION 4 / VRAAG 4
4.1 The acceleration of an object is directly proportional to the net force acting (2)
on the object, is in the direction of the net force, and is inversely
proportional to the mass of the object.

0.93 kg block 1.5 kg block

4.2.2 Consider the 0.93 kg block (7)

Fnet = ma = FT

0.93a = FT  ……………..(1)

Consider the 1.5 kg block

Fnet = m a = Fapp - FT

1.5 a  = 6.4 – FT  ……………….. (2)

(2) + (1)

0.93 a + 1.5 a = 6.4 

Therefore a = 2.63 m/s2

4.2.3 Consider the 0.93 kg block. Consider the 1.5 kg block (3)
FT = ma m a = Fapp - FT 
FT = 0.93 × 2.63 1.5 x 2.63 = 6.4 - FT 
FT = 2.45 N  FT = 2.45 N 

QUESTION 5 / VRAAG 5

5.1. Any two objects in the universe attract each other √ with a force directly (2)
proportional to the product of their masses√ and inversely proportional to
the square of the distance between their centres√ Elke partikel in die
heelal trek elke partikel aan met ‘n krag wat direk eweredig is aan die
produk van hulle massas, en omgekeerd eweredig is aan die kwadraat
van die afstand tussen hulle.

5.2 . where 𝑅 is the distance between the centres of the two

Waar R die afstaand is tussen die twee (5)

ℎ𝑒𝑖𝑔ℎ𝑡 = 𝑅 − 𝑟 where 𝑟 is the radius of the earth
