A car whose mass is 1000 kg is traveling at a constant speed of 10 m/s Neglecting any friction, how much force will the engine have to supply to keep going the same speed?
neglecting all friction? Shut off the engine, the same speed keeps constant.

To determine the force required to keep the car moving at a constant speed, we need to use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).
In this case, since the car is traveling at a constant speed, there is no acceleration. Therefore, the equation simplifies to F = m * a, where acceleration is zero.
Since the car is moving in a straight line at a constant speed, there must be a net force acting on it to counteract any opposing forces, such as friction, and maintain a constant speed. This net force is called the "force of propulsion" or simply the driving force.
Since there is no friction mentioned in the problem, the only force acting on the car is the force of propulsion generated by the engine to counteract any other forces.
Hence, the engine would have to supply a force equal to zero to keep the car going at the same speed, as there are no opposing forces mentioned.
