Question

Вагонетка массой 200 кг движется с ускорением 4м/с^2. С какой силой рабочий толкает вагонетку, если коэффицент трения равен 0,6

Answer 1

Дано:
m=200кг
g=4м/с2
Fтр=0,6
F-?
Решение:
F=m*a=200*4=800
Ft=N*f=mg*f=200*10*0.6=1200
итого надо Ft+F=1200+800=2000

Answer 2

Calculation of the Force

To calculate the force with which the worker pushes the wagon, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration. In this case, the mass of the wagon is 200 kg and the acceleration is 4 m/s^2.

Using the formula F = m * a, where F is the force, m is the mass, and a is the acceleration, we can calculate the force as follows:

F = 200 kg * 4 m/s^2 = 800 N

Therefore, the worker pushes the wagon with a force of 800 Newtons.
