What net force is needed to accelerate a 1.6 × 103kg automobile forward at 2.0 m/s2?
F=ma
To determine the net force needed to accelerate an object, you can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.
The equation for Newton's second law is:
F = m * a
Where:
F represents the net force applied to the object,
m represents the mass of the object, and
a represents the acceleration of the object.
In this case, the mass of the automobile is given as 1.6 × 10^3 kg, and the acceleration is given as 2.0 m/s^2.
Substituting these values into the equation, we have:
F = (1.6 × 10^3 kg) * (2.0 m/s^2)
Now, we can calculate the net force:
F = 3200 kg·m/s^2
So, the net force needed to accelerate the automobile forward at 2.0 m/s^2 is 3200 N (Newtons).
