Question

The following is a graph of the velocity of an object moving along a line with respect to time. Positive direction is away from the motion detector.

1. From the following choose all that are correctly describing the motion at time t = 8 s.(Can have more than 1 answer)

a. The acceleration is positive.

b. The object is moving towards the detector.

c. The acceleration is negative.

d. The object is moving away from the detector.

2. According to the above graph, which of the following is correct?

a. The object is the farthest away from the detector at time t = 6 s.

b. The object's position does not change during the time interval from t = 4 s to t = 6 s.

c. The object is the farthest away from the detector at time t = 10 s.

d. The object's position at time t = 10 s is the same as its position at time t = 0 s.

1) a. False b. False c. True d. True 2) a.False b.False c.True d. False
