Question

uppose a cart 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 cart, the graph appears as a straight line with positive slope starting at the origin 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 along the x (time) axis a parabola, open upward a straight line parallel to the x (time) axis and above the x-axis a straight line along the y-axis a parabola, open downward 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 b) If you plot velocity vs. time for the cart, 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 positive slope starting at the origin a straight line along the y-axis a parabola, open downward a parabola, open upward a straight line parallel to the x (time) axis and above the x-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 with positive slope, starting from a point on the positive y-axis c) If you plot acceleration vs. time for the cart, the graph appears as a parabola, open upward a straight line with positive slope starting at the origin a straight line along the y-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 along the x (time) axis a parabola, open downward 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 above the x-axis a straight line parallel to the x (time) axis and below the x-axis

Explanation / Answer

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