Question
A car accelerates on a horizontal road due to the force exerted by
Solution
the engine. The force exerted by the engine causes the wheels to turn, which pushes the car forward. This force is opposed by various other forces such as air resistance and friction between the tires and the road. If the force exerted by the engine is greater than these opposing forces, the car will accelerate. The rate of acceleration depends on the magnitude of the force and the mass of the car, according to Newton's second law of motion (Force = mass x acceleration). Therefore, the greater the force or the smaller the mass, the greater the acceleration.

An automobile traveling at a speed of 29.2 m/s applies its brakes and comes to a stop in 4.96 s. If the automobile has a mass of 1.39 × 103 kg, what is the average horizontal force exerted on it during braking? Assume the road is level. Enter a positive answer if the force is with the car's direction of motion, and a negative answer if it is opposite the car's direction of motion.
If a car is traveling at a constant speed on a straight road, what can you say about the net force acting on it?
A car moves at constant speed. The horizontal forces acting on the car are friction and the driving force.If the car continues to move with constant (uniform speed), what can be said about the horizontal forces? Group of answer choicesThe friction force is greater than the force due to friction.The horizontal forces are always equal to the force due to gravityThe driving force is greater than the force due to friction.The driving force is equal to the force due to friction.
