Question

Санки массой 50 кг вместе с мальчиком тянут горизонтально с силой 700Н. Сила трения полозьев о снег 50Н. С каким ускорение движутся санки??? ПОЖАЛУЙСТА ВЫРУЧАЙТЕ!!!!ЗАРАНЕЕ СПАСИБО!!!

Answer 1

Ответ:

Fтяги-Fтрения=m*a

700H-50H=50кг*а

а=13 м/с^2

Answer 2

To find the acceleration of the sled, we can use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration. In this case, the net force is the difference between the applied force and the force of friction.

Given information:

- Mass of the sled and the boy (m): 50 kg - Applied force (F_applied): 700 N - Force of friction (F_friction): 50 N

Calculating the acceleration:

To find the acceleration, we need to determine the net force acting on the sled. The net force is the difference between the applied force and the force of friction:

Net force (F_net) = F_applied - F_friction

Substituting the given values:

F_net = 700 N - 50 N = 650 N

Now, we can use Newton's second law to find the acceleration:

F_net = m * a

Substituting the values:

650 N = 50 kg * a

Solving for acceleration (a):

a = 650 N / 50 kg = 13 m/s^2

Therefore, the sled is moving with an acceleration of 13 m/s^2.

Please note that the answer provided is based on the information given and assumes ideal conditions.
