Question

Помогите срочно... пожалуйстаНа брусок массой 200 гр действуют 2 силы: F1=1H, направленная на юг, и сила F2=1.5H, направленная на север. С каким ускорением движется брусок?

Answer 1

Переводим массу в СИ: 0,2 КГ, так как Ф1 и Ф2 противоположно направленные, то равнодействующая 0.5 Н, F = ma, значит а = 0.5 / 0.2 = 2.5 м.с2

Answer 2

Calculation of Acceleration

To calculate the acceleration of the block, we need to consider the net force acting on it. The net force is the vector sum of the individual forces acting on the block.

In this case, we have two forces acting on the block: F1 = 1H (directed south) and F2 = 1.5H (directed north). Since the forces are in opposite directions, we need to subtract them to find the net force.

The net force (F_net) can be calculated as:

F_net = F2 - F1

Substituting the given values:

F_net = 1.5H - 1H

Now, we can calculate the acceleration (a) using 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:

F_net = m * a

Rearranging the equation to solve for acceleration:

a = F_net / m

Substituting the given mass of the block (m = 200 g = 0.2 kg) and the calculated net force (F_net), we can find the acceleration.

Let's calculate the net force and acceleration.

Calculation Steps:

1. Convert the mass of the block from grams to kilograms: - 200 g = 0.2 kg

2. Calculate the net force: - F_net = F2 - F1 - F_net = 1.5H - 1H - F_net = 0.5H

3. Calculate the acceleration: - a = F_net / m - a = 0.5H / 0.2 kg - a = 2.5 H/kg

Therefore, the block is moving with an acceleration of 2.5 H/kg.

Please note that the unit "H" used in the question is not a standard unit of force. It is important to use consistent units when performing calculations. If you provide the correct unit of force, we can provide a more accurate answer.
