DT Lab Questions
1. A motorist drives north for 10 minutes at 80 km/h and then stops for 15 minutes. He then continues north, traveling 130 km in 2 h. (a) What is his total displacement? (b) What is his average velocity?
2. A tennis player moves in a straight-line path as shown in the figure. On the vertical axis in the figure,x1 = 3 m and x2 = -2 m. Find her average velocities in the time intervals (a) 0to 1.0 s, (b) 0 to 4.0 s, (c) 1.0 s to 5.0 s, and (d) 0 to 5.0 s.
3. The velocity-versus-time graph for an object moving along a straight path is shown in the figure. On the vertical axis in the figure,v1 = 10 m/s. (a) Find the average acceleration of this object during the time intervals (a) 0 to 5.0 s, (b) 5.0 s to 15 s, and (c) 0 to 20 s. Find the instantaneous accelerations at (d) 2 s, (e) 10 s, and (f) 18s.
