All parts and working needed. Tutorial: Oscillations II. Reading information from displacement vs. time graph The graph from the previous situation is labeled below with eight points A-H. For each question below, choose from the labeled points above or state "none." Displacement, cm A. Kinematic quantities 1. At which point or points is the velocity negative? Explain. 2 At which point or points is the acceleration positive? Explain. 3. At which point or points is the net force on the cart equal to zero? Explain. At which point or points doss the cart have zero velocity butnero net fore? Esplain. 5. At which point or points are the acceleration, velocity, and displacement all positive? Explain. 6. At which point or points is the acceleration nonzero and opposite in sign to the position? Explain. 7. At which point or points is the velocity nonzero and opposite in sign to the acceleration? Explain.

Explanation / Answer

1) at points B, C,D the velocity of the particle is zero since the slope of displacement time curve is negative

2) at points B and F the acceleration of the particle is positive since in these region velocity is increasing

3) displacement is zero at equilibrium which is at displacement zero

So at C and G force is zero

4) A and F are the points where displacement is maximum so at maximum displacement particles velocity is zero
