PLEASE HELPPP !! A 6kg object experiences a force of 15N to the right and 2N to the left.
What is its resulting acceleration?

Let's calculate the acceleration on the right:

F = m*a

15N = 6kg * a

a = 15/6 m/s^2

On the left:

2N = 6k * a

a = 1/3 m/s^2

---

Note: they gave you horrible data since the accelerations are not natural numbers but fine. If you want, you can calculate how much is 15/6 and 1/3 so you get a better result.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
