If we apply the above equations to the case of an object that does not change its direction of travel as it moves with constant acceleration, we find that the object: Undergoes a displacement Ax = x- x, . Note that displacement is a positive quantity if x > x, and a negative quantity if x < x,. Has average velocity v = (x - x )/t = (v + vo)/2. Note that velocity has the same sign as displacement. Travels distance d = |Ax| = |x – x,| . Note that distance is always a positive quantity. Has average speed d/t . Note that speed is always a positive quantity. Has constant acceleration a = (v – vo)/t . Acceleration may be positive or negative, depending on how velocity changes. - Xo For the case of an object that does change its direction of travel as it moves with constant acceleration, which of the quantities listed above are different?

Sure, I can help with that! For the speed vs base graph, we will plot the average velocity for each of the ramp angles (20°, 30°, 45°, 60°, and 70°) on the y-axis, and the distance travelled (base) on the x-axis. For the speed vs height graph, we will plot the average velocity for each of the ramp angles on the y-axis, and the height of the ramp on the x-axis. For the speed vs slope graph, we will plot the average velocity for each of the ramp angles on the y-axis, and the slope of the ramp (rise over run) on the x-axis. now using this information creat these 3 graphs for the table down below, Ramp angle in degrees Distance (in m) time 1 (s) time 2 (s) time 3 (s) T-avg Velocity(m/s) 20 1.7 0.8 0.7 0.9 0.8 2.125 m/s 30 1.5 0.9 1.1 1.0 1.0 1.5 m/s 45 2 1.2 1.3 1.4 1.4 1.54 m/s 60 1.8 1.5 1.6 1.7 1.7 1.125 m/s 70 1.9 1.6 1.8 2.0 2.0 1.06 m/s
