Question35. Do this problem on a worksheet. Both car A and car B leave school when a clock reads zero. Car A travels at a constant , and car B travels at a constant . a. Draw a position-time graph showing the motion of both cars. b. How far are the two cars from school when the clock reads 2.0 h ? Calculate the distances using the equation for motion and show them on your graph. c. Both cars passed a gas station 120 km from the school. When did each car pass the gas station? Calculate the times and show them on your graph.
Studdy Solution
Determine the time each car passes the gas station 120 km from the school using the equation for motion: .
- For Car A:
$ \text{Time}_A = \frac{120 \, \text{km}}{75 \, \text{km/h}} = 1.6 \, \text{h}
\]
- For Car B:
$ \text{Time}_B = \frac{120 \, \text{km}}{85 \, \text{km/h}} \approx 1.41 \, \text{h}
\]
- Mark these times on the graph where each car passes the 120 km mark.
