If Experiment 1 were repeated with a plane length of 4 meters, the movement time for the wood block, in seconds, would be closest to:
A. 2.31
B. 1.64
C. 1.32
D. 0.64

Experiment 1
The group of students wanted to know which materials moved down the plane in the shortest amount of time. The students used blocks of wood, steel, aluminum, glass, plastic, and concrete. The dimensions of each block were the same, the volume of each block remained constant, and the mass of the blocks was varied. The incline of the plane was set at 45◦ for each trial. The students conducted 3 trials for each material, and recorded the results in Table 1.
