What is the constant rate of change from the graph?

1/47

94

47

1/94

Step-by-step explanation:

The constant rate is defined as

Where and are two points on the line.

Let's use points (0,0) and (6,282).

Therefore, the constant rate of from the graph is 47.

So, the right answer is the third choice.

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
