True False I observed that as time increased, the acceleration vector stayed the same length. True False Part II: Questions Part III: Data Complete Table 3. For this part of the data entry, record all data to the nearest whole number. Do not include units in your answer. Table 3 Initial Settings Readings from the Graphs Describe Distance (m) Time (s) Velocity (m/s) Acceleration (m/s2) x = 0.00 m v = 10.0 m/s a = 2.00 m/s2 WebAssign will check your answer for the correct number of significant figures. 25.00 WebAssign will check your answer for the correct number of significant figures. 5.000 WebAssign will check your answer for the correct number of significant figures. -10.37 WebAssign will check your answer for the correct number of significant figures. -2.00 Position (x) vs. Time graph Velocity (v) vs. Time graph Acceleration (a) vs. Time graph Part III: Questions Please include units in your answer. • Use the correct unit abbreviation. • Include a space between the value and the unit. • To express exponents in your units, use a ^. For example, m/s2 would be m/s^2. What is the value of the acceleration? Describe what happens to the velocity vector as the car goes forward and then returns to 0.00 m. The velocity vector increases until it gets to 25 m; it then changes direction and decreases to the left. The velocity vector decreases until it gets to 25 m; it then changes direction and increases to the left. The velocity vector decreases until it gets to 25 m; it then changes direction and decreases to the left. The velocity vector does not change length. From the Position vs. Time graph, read the furthest distance the car reaches from the starting point. From the Position vs. Time graph, what is the time that the car reaches this furthest distance? Using the time you found in the previous question and looking at the Velocity vs. Time graph, what is the velocity at this time? Using the time you found above and looking at the Acceleration vs. Time graph, what is the acceleration at this time? Considering your last two answers, is it possible for an object to have zero velocity while at the same time having a nonzero acceleration? Yes No

Explanation / Answer

Yes, Under gravity when any particle reach at the maximum height velocity becomes zero and acceleration due to gravity is g.
