F=ma where f is force, m is mass, and a is acceleration.
The net force is 40-24=16N and the box is 8kg.
You can rearranage f=ma to make a the subject by dividing by m, so f/m=a
16/8=2m/s^2

Answer: #.37 times greater
Explanation: Volume of a sphere is: V = ·π·r³
Since it is given the diameter of the basketball and the softball, their ratios are r₁ = 3in and r₂ = 2in, in which index 1 represents the basketball and index 2, the softball.
Calculating the volume of basketball:
V₁ = . 3.14 . 3³
V₁ = 113.04 in³
Calculating the volume of softball:
V₂ = . 3.14 . 2³
V₂ = 33.5 in³
Comparing one volume with the other:
= = 3.37
We have that V₁ = 3.37V₂
This means the volume of a basketball is 3.37 times greater than the volume of a softball.
Answer:
The solid begins to go from a solid state to a liquid state — a process called melting.
