All, I am reviewing for a comprehensive exam and am extremely weak on 1D Motion. Can you please help me out?
A lab cart travels along the x-axis and its position as a function of time is given by the following expression: x(t)= 6m - (8 m/s)t + (1 m/s2)t2
1. Displacement of cart during time interval t=0s to t=2s
2. [tex]\Delta[/tex]x of cart during time interval t=2s to t=3s.
3. [tex]\Delta[/tex]x of cart during time interval t=0s to t=5s.
4. Total distance from t=0s to t=5s.
5. Initial velocity (@t=0) in m/s.
6. Average velocity from t=0s to t=5s.
7. Average speed (m/s) t=0s to t=5s.
8. Instantaneous velocity (m/s) @ t=3s.
9. Acceleration in (m/s2)
10. Where (if ever) does the cart change direction?
