Question

К телу массой 2кг приложена сила 10Н,вызывающая движение тела.Если сила трения равна 4Н,то ускорение тела?

Answer 1

m*a=F-Fтр=2*a=10-4

a=(F-Fтр)/m=(10-4)/2=3 м/с^2

Answer 2

Calculation of Acceleration

To calculate the acceleration of the body, we need to consider the forces acting on it. In this case, a force of 10 N is applied to a body with a mass of 2 kg. The force of friction is given as 4 N.

The equation to calculate acceleration is:

F_net = ma

Where: - F_net is the net force acting on the body - m is the mass of the body - a is the acceleration of the body

In this case, the net force is the difference between the applied force and the force of friction:

F_net = F_applied - F_friction

Substituting the given values:

F_net = 10 N - 4 N = 6 N

Now we can calculate the acceleration:

F_net = ma

6 N = 2 kg * a

Solving for a:

a = 6 N / 2 kg = 3 m/s^2

Therefore, the acceleration of the body is 3 m/s^2.
