Answer:
i think option C is correct answer
Explanation:
Average speed = change in distance / change in time
In other words, the average speed is the slope of the line connecting two points on the graph.
Force can be obtained by multiplying the mass of the object times the acceleration. Since all of the needed values are given, solving is done as shown below:
Force = mass x acceleration
Force = 0.25 kg x 15.5 m/s^2
Force = 3.875 N
Among the choices, the correct answer is C. 3.87 N
