Suppose a glider slides from rest down a frictionless PASCO track tilted at some

Question

Suppose a glider slides from rest down a frictionless PASCO track tilted at some angle ?. Assume:
- Down the incline is positive
- The origin is at the top of the track.

a) If you plot displacement vs. time for the glider, the graph appears as

a parabola, open downward
a straight line with positive slope, starting from a point on the positive y-axis
a straight line with negative slope, starting from a point on the positive y-axis
a straight line along the x (time) axis
a straight line parallel to the x (time) axis and above the x-axis
a straight line parallel to the x (time) axis and below the x-axis
a straight line along the y-axis
a parabola, open upward
a straight line with positive slope starting at the origin
a straight line with negative slope starting at the origin


b) If you plot velocity vs. time for the glider, the graph appears as

a straight line with positive slope starting at the origin
a straight line with negative slope, starting from a point on the positive y-axis
a straight line with positive slope, starting from a point on the positive y-axis
a straight line parallel to the x (time) axis and below the x-axis
a parabola, open downward
a straight line parallel to the x (time) axis and above the x-axis
a straight line along the y-axis
a parabola, open upward
a straight line along the x (time) axis
a straight line with negative slope starting at the origin


b) If you plot acceleration vs. time for the glider, the graph appears as

a straight line parallel to the x (time) axis and below the x-axis
a straight line with negative slope starting at the origin
a straight line with negative slope, starting from a point on the positive y-axis
a straight line with positive slope, starting from a point on the positive y-axis
a straight line with positive slope starting at the origin
a parabola, open downward
a straight line along the y-axis
a parabola, open upward
a straight line parallel to the x (time) axis and above the x-axis
a straight line along the x (time) axis

Explanation / Answer

a) a parabola, open upward f) a straight line parallel to the x (time) axis and above the x-axi
