To find the mass of the object, you can use Newton's second law of motion, which states that the force (F) applied to an object is equal to the mass (m) of the object times its acceleration (a), or F = ma.
From the given data, you have the following information:
Force (F) = 30 N, 70 N, and 85 N
Acceleration (a) = 1.5 m/s^2, 3.5 m/s^2, and 4.25 m/s^2
Let's calculate the mass for each set of data and see if they are consistent:
For the first set of data (30 N and 1.5 m/s^2):
m1 = F1 / a1 = 30 N / 1.5 m/s^2 = 20 kg
For the second set of data (70 N and 3.5 m/s^2):
m2 = F2 / a2 = 70 N / 3.5 m/s^2 = 20 kg
For the third set of data (85 N and 4.25 m/s^2):
m3 = F3 / a3 = 85 N / 4.25 m/s^2 = 20 kg
The calculated mass is consistent at 20 kg for all the data sets. So, the mass of the object experimented on is 20 kg.
The correct answer is:
c) 20 kg
