Question

под действием силы 4 н тело движется с ускорением 80 cм/c в кубе. Какова масса тела?

Answer 1

F=m*a

 

m=F/a

 

a=0.8 м/с²

 

F=4 H

 

m=4/0.8=5 кг

Answer 2

Calculation of the mass of the object

To calculate the mass of the object, 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. The formula is as follows:

F = m * a

Where: - F is the force acting on the object - m is the mass of the object - a is the acceleration of the object

In this case, the force acting on the object is given as 4 N (newtons), and the acceleration is given as 80 cm/s^2 (centimeters per second squared). To convert the acceleration to meters per second squared, we divide it by 100:

a = 80 cm/s^2 = 0.8 m/s^2

Now we can rearrange the formula to solve for the mass of the object:

m = F / a

Substituting the given values:

m = 4 N / 0.8 m/s^2 = 5 kg

Therefore, the mass of the object is 5 kg.
