2.2.1 Represent and reason A car moves west at 40 m/s on a straight highway. The car's motion at the time we start describing it is presented in the illustration below using three different reference frames. Note the description in the first reference frame. Answer the following questions. x (m) -200 -100 100 200 1o = 0, xo = 0, Vo = -40 m/s x (m) 100 0. - 100 -200 . -300 6 = 0, xo = -100 m t. x (m) 0. 100 200 300 400 to = 0, xo = +200 m a. What is the car's velocity in the two other reference frames? A bicycle moves east at constant speed on the same straight road. The bicycle's motion is described in the illustratio below at one particular time using one coordinate system. Describe the bicycle's location and velocity at the same ti using the last two coordinate systems shown in the illustration for part a. x (m) -200 -100 100 200 to = 0, xo = -200 m, vo = 10 m/s

Question
**2.2.1 Represent and reason** A car moves west at 40 m/s on a straight highway. The car’s motion at the time we start describing it is presented in the illustration below using three different reference frames. Note the description in the first reference frame. Answer the following questions. **Illustration Description:** There are three horizontal axes labeled with distances in meters (m): 1. **First reference frame**: - Scale: -200, -100, 0, 100, 200 - At \( t_0 = 0 \), \( x_0 = 0 \), \( v_0 = -40 \, \text{m/s} \) 2. **Second reference frame**: - Scale: 100, 0, -100, -200, -300 - At \( t_0 = 0 \), \( x_0 = -100 \, \text{m} \) 3. **Third reference frame**: - Scale: 0, 100, 200, 300, 400 - At \( t_0 = 0 \), \( x_0 = +200 \, \text{m} \) **Questions:** a. What is the car’s velocity in the two other reference frames? **b.** A bicycle moves east at constant speed on the same straight road. The bicycle’s motion is described in the illustration below at one particular time using one coordinate system. Describe the bicycle’s location and velocity at the same time, using the last two coordinate systems shown in the illustration for part a. **Bicycle Illustration Description:** - Scale: -200, -100, 0, 100, 200 - At \( t_0 = 0 \), \( x_0 = -200 \, \text{m} \), \( v_0 = 10 \, \text{m/s} \)
