Question

Какую силу надо приложить к телу, движущемуся со скоростью 4м/с под углом 300 если мощность 480Вт

Answer 1

N=F*V*cosa
F=N/V*cosa=480/4*0,866=138,6 Н

Answer 2

Calculation of the Force

To calculate the force required to move an object at a certain speed and angle, we need to use the formula:

Force = Power / Velocity

Given that the power is 480 Watts and the velocity is 4 m/s, we can substitute these values into the formula to find the force.

Force = 480 W / 4 m/s

Calculating this, we find that the force required is 120 Newtons.

Conclusion

To move an object with a velocity of 4 m/s at an angle of 300 degrees, a force of 120 Newtons needs to be applied.
