What is the power of an engine that pulls a 1000kg automobile at a steady speed of 10m/s along a level road?

To determine the power of an engine, we need to know two things: the force acting on the automobile and the speed at which it is moving. Since the automobile is moving at a steady speed of 10 m/s along a level road, we know that the net force acting on it is zero, as there is no acceleration. The force needed to counteract the resistive forces (such as friction and air resistance) and maintain this constant speed is equal in magnitude but opposite in direction to the total resistive force.

To calculate the power, we can use the formula:

Power = Force x Velocity

In this case, the force acting on the automobile is the force required to overcome the resistive forces. Since the net force is zero, the force required to counteract these forces is also zero. Therefore, the power required to maintain a steady speed of 10 m/s is also zero.

Hence, the power of the engine pulling the 1000 kg automobile at a steady speed of 10 m/s on a level road is zero.

0 HP

if there is no friction, pulling at a steady speed on a level road does not do work.

If there is kinetic friction μk, then

F=force = μk * mg
v=velocity = 10 m/s

Power = F.v j/s = F.v watts

Steady speed means zero acceleration.

Since power=force*velocity and force is zero due to steady speed then power will also be zero.
In other words; power=force*velocity
Power=mass*acceleration *velocity
Since acceleration is zero.
Power=mass*0*velocity
Power=0hp OR 0watts
