Question

Определите вес чемодана массой 5 кг лежащего в багажнике автомобиля если автомобиль резко тормозит с ускорением 10 м/с в квадрате??

Answer 1

Р=mg=5*9.8=50 [H], а т.к. ускорение действует вдоль оси параллельной поверхности земли значение иметь не будет(его во внимание не берем)

Answer 2

Calculation of the Weight of the Suitcase

To determine the weight of the suitcase, we need to consider the force acting on it when the car suddenly brakes with an acceleration of 10 m/s². The force acting on an object can be calculated using Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a):

F = m * a

In this case, the force acting on the suitcase is equal to its weight (W), which can be calculated using the formula:

W = m * g

where m is the mass of the suitcase and g is the acceleration due to gravity (approximately 9.8 m/s²).

To find the weight of the suitcase, we need to solve the equation for m:

m = W / g

Given that the mass of the suitcase is 5 kg and the acceleration due to gravity is 9.8 m/s², we can substitute these values into the equation to find the weight of the suitcase:

W = (5 kg) * (9.8 m/s²)

Calculating this, we find:

W = 49 N

Therefore, the weight of the suitcase is 49 Newtons when the car suddenly brakes with an acceleration of 10 m/s².
