Motion in Two Dimensions Questionnaire
1. A car travels 84.8 meters in the x-direction and 83.6 meters in the y-direction. The total travel time is 5.72 seconds. Find the magnitude of the car’s average velocity. Magnitude of the average velocity = m/s
2. A car travels 16.3 m 24.3 degrees north of east and then travels 10.8 m 54 degrees north of east. What is the car’s overall displacement?
3. An object moves from point A to point B along a given path. What must be known in order to calculate displacement? Choose all that apply.The positions of points A and BThe time required to move from point A to point BThe instantaneous velocity at the starting and ending pointsThe length of the path
4. A student rides a bicycle in a semi-circular (half-circle) path, which takes 5.2 seconds. If the diameter of the semi-circle is 7.51 m, find the magnitude of the student‘s velocity during the trip.
