Question

Помогите пожалуйста Двигатель поднимает груз:m=5кг;h=60см;t=2с Определите:F;A;N

Answer 1

Ответ: 50Н; 30Дж; 15Вт

Объяснение:

Дано:

m=5кг;

h=60см=0,6м;

t=2с

Определите:F;A;N

F=п=5*10=50Н

А=Fh=50*0,6=30Дж

N=А/t=30/2=15Вт

Answer 2

Calculation of Force, Work, and Power

Given: - Mass (m) = 5 kg - Height (h) = 60 cm - Time (t) = 2 s

Force (F)

To calculate the force (F) required to lift the mass, we can use the formula: F = m * g, where: - m = mass (5 kg) - g = acceleration due to gravity (approximately 9.81 m/s^2)

Substitute the given values: F = 5 kg * 9.81 m/s^2 F ≈ 49.05 N

Therefore, the force required to lift the mass is approximately 49.05 N.

Work (W)

The work done in lifting the mass can be calculated using the formula: W = F * h, where: - F = force (49.05 N) - h = height (60 cm = 0.6 m)

Substitute the given values: W = 49.05 N * 0.6 m W ≈ 29.43 J

Therefore, the work done in lifting the mass is approximately 29.43 J.

Power (P)

The power can be calculated using the formula: P = W / t, where: - W = work (29.43 J) - t = time (2 s)

Substitute the given values: P = 29.43 J / 2 s P ≈ 14.715 W

Therefore, the power required to lift the mass in this scenario is approximately 14.715 W.
