The driver of an 1,840 kg race car applies the brake to come to a complete stop. If the car accelerates at -3.4 m/s2 what is the net force acting on the race car?
To find the net force acting on the race car, you can use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration.
The given acceleration is -3.4 m/s^2, which means that the car is decelerating (slowing down). The negative sign indicates the direction of the acceleration.
The mass of the race car is given as 1,840 kg.
Using the formula for net force, we can calculate:
Net Force = Mass × Acceleration
Net Force = 1,840 kg × (-3.4 m/s^2)
Net Force = -6,256 N
So, the net force acting on the race car is -6,256 Newtons (N). The negative sign indicates that the force is acting in the opposite direction of the car's motion.
F = ma
