Question

автомобиль массой 1500кг начинает двигаться горизонтально с ускорением 0,5 м/с . сопротивление движению 500 Н . определите силу тяги, развиваемую двигателем.

Answer 1

Calculation of the Engine Thrust Force

To determine the thrust force developed by the engine, we need to consider the mass of the car, the acceleration, and the resistance to motion.

Given: - Mass of the car = 1500 kg - Acceleration = 0.5 m/s^2 - Resistance to motion = 500 N

To calculate the engine thrust force, we can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration (F = m * a). In this case, the force is the engine thrust force.

Using the given values: - Mass (m) = 1500 kg - Acceleration (a) = 0.5 m/s^2

We can substitute these values into the formula to calculate the engine thrust force:

F = m * a

F = 1500 kg * 0.5 m/s^2

F = 750 N

Therefore, the engine develops a thrust force of 750 Newtons.

Please note that this calculation assumes that the resistance to motion remains constant throughout the acceleration process.
