In the lab you explored how a lioness can catch a gazelle despite the fact that the lioness' top speed is slower than gazelle's, and gazelle has a distance head start during the chase. The graph below uses the same approximations you did in the lab and assumes that the lioness and the gazelle have constant accelerations until the they reach their top speeds. 30 Velocity, mis 20 0 0 5 10 15 20 25 Time,s If lioness gave up an unsuccessful chase at the moment she reached her top speed, what was the minimal separation between the gazelle and the lioness at the start of the chase. Use the information given to you on the graph above for all parameters you need to answer the question. Assume that the gazelle had a head start in distance, but no head start in time.

A motorist starts from rest and traveled as seen in the speed-time graph. The total distance traveled and the average velocity in m/s for the distance traveled is 1.5 3.0 4.5 6.0 7.5 Time in minutes Select one: O a. 7.5 km, 4.5 m/s b. 10 km, 1.5 m/s c. 4.5 km, 10 m/s Reply... Speed in km/h :

A motorist drove from Bristol to Bath at an average speed of 40 mph and then from Bath to Chippenham at an average spped of 30 mph. What was her average speed for the whole journey? A. 35 mph B. 36 mph C. 70 mph D. need more information

The figure below shows velocity-versus-time graphs for two objects, A and B. What can we say about the distance between objects A and B? Vy The distance between A and B is always increasing. The distance between A and B first decreases and then increases. The distance between A and B is always decreasing. The distance between A and B first increases and then decreases. The distance between A and B remains constant. O O O O O
