Question

M=60т fтяж=90k/H m=0,05 а-?

Answer 1

M = 60 т = 60 000 кг - масса грузовика
μ = 0.05 - коэф сопротивления
f = 90 000 Н - сила тяги
a = F/M = (f - Mgμ)/M = f/M - gμ = 90 000/60 000 - 10*0.05 = 1.5 - 0.5 = 1 м/с²

Answer 2

To solve the equation, I'll assume that you're looking for the acceleration (a) and I'll use the given values:

M = 60 t (mass in metric tons) fтяж = 90 kN/h (force in kilonewtons per hour) m = 0.05 (acceleration in meters per second squared)

To find the acceleration (a), we can use Newton's second law of motion:

F = ma

First, let's convert the given mass from metric tons to kilograms: 1 metric ton = 1000 kilograms So, M = 60 t = 60 * 1000 kg = 60000 kg

Next, let's convert the given force from kilonewtons per hour to newtons: 1 kilonewton = 1000 newtons 1 hour = 3600 seconds So, fтяж = 90 kN/h = 90 * 1000 N / 3600 s ≈ 25 N/s

Now we can substitute the values into Newton's second law:

25 N/s = 60000 kg * a

Simplifying the equation, we can solve for a:

a = 25 N/s / 60000 kg a ≈ 0.00042 m/s²

Therefore, the approximate value of the acceleration (a) is 0.00042 m/s².
