Question

The baggage truck A has a mass of 800 kg and is used to pull each of the 300-kg cars. If the tractive force F on the truck is = 480 N, determine:

a) The initial acceleration of the truck.

b) Forces in coupling B and C.

c) What is the acceleration of the truck if the coupling at C suddenly fails?

The car wheels are free to roll. Neglect the mass of the wheels.

answer asap.

Answer 1

$F=ma$

$m =m_1+m_2 = 800+300=110000 kg$

Initial acceleration of the truck

$a =\frac{F}{m} =\frac{480}{110000}=0.00436 \frac{m}{s}$
