Question
In the experiment below, a student pulled each of three blocks in a straight line across a flat, horizontal surface. Figure 1 shows the results of the student measuring the PULLING FORCE (the force required to move each block at a constant speed) of the three trial. The data plots the pulling force in newtons (N), versus the block mass, in kilograms (kg)
Based on Figure 1 (below) an applied pulling force of 30.00 N would most likely have been required to maintain the constant speed of a block having a mass of:

To determine the mass of the block that would require an applied pulling force of 30.00 N to maintain a constant speed, we would ideally refer to the data points shown in Figure 1. However, since we do not have access to the actual figure, we can make an educated guess based on the typical relationship between pulling force and block mass.
In general, the pulling force required to maintain a constant speed of a block on a surface usually increases linearly with the mass of the block due to friction. Therefore, if we assume that the relationship is approximately linear, we can project that:
- Lower masses (like 4.00 kg, 5.00 kg, etc.) would require less force.
- Higher masses would require correspondingly more force to overcome friction.
Given that a pulling force of 30.00 N is relatively high, it's reasonable to estimate that it would correspond to a heavier block.
If we refer to typical experiments, a pulling force of about 30.00 N would most likely correspond to a block mass greater than the smaller values provided in your list. For example, if we consider that:
- A 4.00 kg block might require around 10-15 N,
- A 5.00 kg block might require around 15-20 N,
- A 6.00 kg block might approach 20-25 N,
- A 7.00 kg block could require around 25-30 N or more.
Thus, based on this pattern, it would be logical to conclude that a pulling force of 30.00 N would most likely be required to maintain a constant speed for a block with a mass of:
**7.00 kg.**
