Question

The chart shows data for an object moving at a constant acceleration.

A 2 column table with 4 rows. The first column is labeled time in seconds with entries 0, 1, 2, 3. The second column is labeled velocity in meters per second with entries 0, X, Y, Z.
Which values best complete the chart?

X: 0
Y: 0
Z: 1
X: 2
Y: 4
Z: 6
X: 3
Y: 3
Z: 3
X: 1
Y: 5
Z: 8

Answer 1

X = 2, Y = 4, Z = 6.

With constant acceleration and v(0)=0 the velocities form an arithmetic sequence v = at. The only choice with equal increments is 2, 4, 6 (acceleration = 2 m/s²).
