A car weighing 1000 kg pulls a car weighing 1500 kg on a cable. What is the pulling force to move with an acceleration of 2 m / s2? What is the pulling force of the cable? Neglect the forces of resistance.
The sum of the car masses m = m1 + m2 = 1000 kg +1500 kg = 2500 kg. The thrust force must make the sum of the masses m move with an acceleration of 2 m / s. 2. According to Newton’s second law, it is calculated by the formula:
F = ma = 2500 kg * 2 m / s2 = 5000 N.
The cable tension is calculated in the same way:
F2 = m2a = 1500 kg * 2 m / s2 = 3000 N.
Answer: Pulling force F = 5000 N. Rope pulling force F2 = 3000 N.
