Can someone who is good at physics answer these question?

Question

Thanks for helping me people these are the questions
1) If an unbalanced force on an object is doubled, what change in acceleration is produced?
2) What is the relationship between the unbalanced force acting on an object and its acceleration?
3) If the mass of an object is doubled, but the unbalanced force acting on it remains the same, what change in the acceleration is produced?
4) What is the relationship between the mass of an object and its acceleration?
5) What is the relationship between the unbalanced force acting on an object and ma, the product of its mass and its acceleration?
6) If a 1 N force accelerates one cart a 0.5 m/s2, what acceleration will a 5 N force produce on a stack of five carts?

Answer 1

1. Since F=ma and mass remains a constant then 2xF means 2xa
2. If it was a balanced force there would be no acceleration. For an unbalanced force
a=F/m

3. since a=F/m 2xm means a/2
4. More mass less acceleration
5. F is ma
6. m=F1/a1
a2=F2/m= F2/(F1/a1)=a1 F2/F1= .5 x 5/1= 2.5N

Have fun

Answer 2

1. According to the Newton's second law, F = ma. The mass of the object is not changing with a change in force. Therefore, if you double the force, you also double the acceleration.

2. The relationship between the unbalanced force acting on an object and its acceleration is that they are directly proportional. If you increase one, the other also increases. The same is true if you decrease one.

3. According to F=ma, if the mass is doubled and the force is the same, then the acceleration would be 1/2.

4. The relationship between the mass of an object and its acceleration is that they are inversely proportional. If you increase the mass of the object, its acceleration decreases. If you decrease the mass of an object, its acceleration will increase.

5. They are the same. Newton's second law of motion states that F = ma.

6. We must first find out the mass of a cart. To do this we use the information in the first part of the question. Rearranging F = ma for mass, we get m = F/a. Substitute our known values in:
m = 1 N / 0.5 m/s2
m = 2 kg

This information can now be used int he second part of the question.
Our force is 5 N. The mass is 5 x 2 kg = 10 kg. Rearranging the equation F = ma for acceleration, we get a = F / m. Substituting in the values we get a = 5 N / 10 kg . We arrive at an answer of 0.5 m/s2.

Answer 3

1) It will be doubled, mass remaining constant.
2) Acceleration is directly proportional to unbalanced force, mass remaining constant.
3) It will be halved.
4) For a given unbalanced force, acceleration is inversely proportional to mass.
5) They are equal.
6) 0.5 m/s^2.
