A bottle rocket experiences a 500 N force to the right and 300 N of air resistance to the left. Will it accelerate to the left,

right, or not accelerate at all?
A box experiences a 20 N force to the left and two different 8 N forces to the right. Will it accelerate to the left, right, or not at all?

A car experiences a 300 N force to the right from the engine and separate 150 N force due to friction and air resistance to the left. Will it accelerate to the left, right, or not at all?

A rope experiences three 400 N forces to the left and three different 410 N forces to the right.

A skateboard is pushed up a hill with a 90 N force to the left and experiences a gravitational force of 100 N to the right


A box experiences a 20 N force to the left and a 19 N frictional force to the right.

<h2>Answer 1) Right </h2><h3> Explanation :  </h3>

To find that the acceleration will be on right or left, we need to find the net force between them.


Which is Net F = 500 N - 300 N = 200 N  


Therefore, the acceleration will be on right side as it has greater difference as compared to left.



<h2>Answer 2) Left </h2><h3> Explanation : </h3>

Here, the right side will have 2 forces of 8 N which gives the total of 16 N.  

Using the net force calculation = 20 N - 16 N = 4 N.


Therefore, the box will accelerate towards left-side.



<h2>Answer 3) Right </h2><h3>Explanation : </h3>

In this case, the car is experiencing +300 N to the right and -150 N on left.


On calculating the net force = +300 N- 150 N = +150 N.


Here, right side has 150 N greater force than left side. Therefore, the car will accelerate towards right.



<h2>Answer 4) Right </h2><h3>Explanation : </h3>

The rope will move towards right as the net force will be 10 N towards right.


By calculating the net force = 410 N - 400 N = 10 N.


This clearly indicates that the rope will move towards right.



<h2>Answer 5) Right </h2><h3>Explanation: </h3>

The skateboard will accelerate towards right as the force will be 10 N more on right than on left.


As the net force will be = 100 N - 90 N = 10 N.


Since, the 10 N more force is on right the acceleration will be on right.



<h2>Answer 6) Left </h2><h3>Explanation : </h3>

The box will experience acceleration towards left as there will be greater 1 N force on left as compared to right.


On calculating the net force = 20 N - 19 N = 1 N


This shows that the box will accelerate on left side.
