Vector Vault & Navigation
A car travels a total distance of 98 meters in an elapsed time interval of 10 seconds.
Q8
What is 9.8 m/s?
A lab cart equipped with a blinking light of constant period moves along a straight track at a constant velocity.
Q9
What is evenly spaced light flashes (Diagram C)?
The velocity of a car changes from $60 m/s North to $45 m/s North in an elapsed time of $5.0 s.
Q5
What is $3.0 m/s^2
According to the Displacement vs. Time graph, this is the object's average speed during the first $4.0 s of travel.
Q2 image
What is 2 m/s
A car travels a distance of 30. kilometers directed due west in an elapsed time of 0.50 hour.
Q10
What is 60. km/hr west?
A locomotive starts from rest and accelerates at $0.12 m/s^2 to a speed of $2.4\ m/s in 20 s, a motion characterized by two concurrent state descriptions.
Q4
What is constant acceleration and increasing velocity?
A $1,000 kg car moving with an initial velocity of +20 m/s decelerates uniformly at a rate of $-5.0 m/s^2 until it comes to rest.
Q6*
Daily Double
What is 40 m?
On the Velocity vs. Time graph for a $2.0 kg cart moving northward, this is the calculated acceleration at time t = 8 s.
Q1
What is 0 m/s^2
A school bus travels a grid route consisting of 400 m East, 500 m North, 400 m East, and 500 m South Evaluating the net vector path relative to total path distance gives this overall magnitude of displacement.
Image for question 11
What is 800 m?
Oil drips at uniform 0.4-second intervals from a leaky car accelerating uniformly from rest, producing a distinct spatial pattern on the road.
Q7
What is pattern B (dots with uniformly increasing separation distance)?
A car traveling due north at 24.0 m/s brakes on a straight highway, recording velocity values across a $4.0 s interval in the host data table. From the initial state to t = 4.0 s, what is the magnitude of the car's average acceleration?
Q12 image
What is 5.0 m/s^2?
On the Velocity vs. Time diagram comparing cars A, B, C, and D, this car demonstrates the greatest acceleration during the time interval from 10 s to 15 s.
Q3
What is Car D?
