You normally drive on the freeway between SanDiego and Los Angeles at an average speed of 105 km/h 165 mi/h2, andthe trip takes 1 h and 50 min. On a Friday afternoon, however, heavytraffic slows you down and you drive the same distance at an averagespeed of only 70 km/h 143 mi/h2. How much longer does the trip take?

You want to visit your friend in Seattle and decide to take the train. Unfortunately, you are late getting to the train station. You are running as fast as you can, but 30 meters ahead of you the train begins to pull out. You can run at a maximum speed of 8 m/s and the train is accelerating at 1 m/s². In 50 meters you will reach a barrier. Can you catch up to the departing train? Argue why you should or should not jump onto the moving train?

Which is the correct answer? Thank you

A racing car is used to test its suspensions and brakes. in a manufacture process. Itis raced and jumped over a ramp. It flies and further on lands at a speed of 44.4m/s. It then slows down at a rate of 15m/s?. How much road is required to bring the car to a complete stop? The car lands 70 meters away from a nearby beach. Will the car run into water?

A train accelerates from 100 m/s west to 170 m/s      west in 10 seconds. What is the acceleration of the       bus?                               a = Vf – Vi                                                     time  7 m/s2 7 m/s2 80 m/s2 280 m/s2    A biker rides 80 meters in 12 seconds.  His average speed is ___. (s=d/t) 15 m/s 67 m/s 58 m/s 92 m/s   According to Newton’s 3rdLaw of Motion, for every action, there is ___. Work being done An equal and opposite reaction An unbalanced force on the reaction.
