Newton's second law:
∑F = ma
170 N = (300 kg) a
a = 0.567 m/s²
Round as needed.
The sled's acceleration is .
Newton's second law of motion states that in an inertial frame of reference the net force acting on an object is equal to the mass m of the object multiplied by its acceleration :
and are vectors and the mass m is a scalar that we assume to be constant. We also assume that the net force and the acceleration are in the horizontal direction x.
We are told that |F| = 170 N and that m = 300 kg. So we get that:
Then the sled's acceleration is
