Answer:
The tension of the rope is 1152 N
Explanation:
Force
Newton's second law states that the acceleration of an object is directly proportional to the net force and inversely related to its mass.
The law can be written as:
F = m.a
The rope must apply a force F to accelerate the car of m=960 Kg at [tex]a=1.2~ m/s^2[/tex]. Given the track is frictionless, all the force applied produces acceleration, thus:
[tex]F = 960~Kg\cdot 1.2~ m/s^2[/tex]
F = 1152 N
The tension of the rope is 1152 N
