Question

(b) Calculate the

(1) friction between the car on tow and the road:
(ii) the forward tractive force of the tow truck, given that the friction on the tow truck is 750 N;
(iii) the resultant force acting on the system of the tow truck
and the car.​

Answer 1

Answer:

AoA!

(i) Resultant force acting on the car, F = ma

=> F = (1000 x 0.5) N = 500 N.

Resultant force = applying force - opposing force(a.k.a. friction)

=> Friction = (1000 - 500) N = 500 N.

(ii) Resultant force acting on the tow truck = ma = (1500 x 0.5) = 750 N.

Apply the same formula: Resultant force = applying force - opposing force(a.k.a. friction)

So forward tractive force = (750 + 750) N = 1500 N.

Hope it helped.
