Answer:
2.1 m/s²
Step-by-step explanation:
The acceleration of a truck that is being moved by a force can be calculated using Newton's second law of motion:
F = ma
where F is the net force acting on the truck, m is the mass of the truck, and a is the acceleration of the truck.
Substituting the given values, we get:
4,200 N = (2,000 kg) a
Solving for a, we get:
a = 4,200 N / 2,000 kg
a = 2.1 m/s²
