- A car is driving on I-80 traveling at 75 mph. It passes a police officer on the side of the road who is stationary. The moment that the car passes the police officer, the officer accelerates at a constant rate of 20 ft/s2 until she reaches a speed of 80 mph. At that point, her speed is maintained. a. How far does the police car travel before reaching its full speed (in ft)? b. How far does the car travel while the police car is speeding up (in ft)? c. How far does the police car travel before catching up with the car (in ft)?arrow_forwardA car is traveling at a steady 80 km/h in a 50 km/h zone. A police motorcycle takes off at the instant the car passes it, accelerating at a steady 8.0 m/s2.a. How much time elapses before the motorcycle is moving as fast as the car?b. How far is the motorcycle from the car when it reaches this speed?arrow_forwardA diver bounces straight up from a diving board, avoiding the diving board on the way down, and falls feet first into a pool. She starts with a velocity of 3.00 m/s, and her takeoff point is 1.60 m above the pool. a. What is her highest point (in m) above the board? b. How long a time (in s) are her feet in the air? c. What is her velocity (in m/s) when her feet hit the water? (Assume the positive direction is upward. Indicate the direction with the sign of your answer.)arrow_forward
- A river has a steady speed of 0.42 m/s. A student swims upstream a distance of 1.3 km and swims back to the starting point. a. If the student can swim at a speed of 1.01 m/s in still water, how long does the trip take? mins (round off to the nearest minute) b. How much time is required in still water for the same length swim? mins (round off to the nearest minute)arrow_forwardAt 10:17 a.m., you pass a police car at 55 mph that is stopped on the freeway. You pass a second police car at 55 mph at 10:53 a.m., which is located 39 mi from the first police car. If the speed limit is 60 mph, can the police cite you for speeding? а. a. The total time between your two police car sightings was P hours. b. Your average speed between the two police car sightings was 8, mph. c. Can the police cite you for speeding? No, your average speed was less than the speed limit. CYes, since your average speed was more than the speed limit, there must have been somewhere within the 39 mi where you were driving more than 60 mph.arrow_forwardA hyena first notices a lion attacking when the lion is 12.5 m away and moving toward the hyena at a speed of 5 m/s. The hyena begins to accelerate away from the lion at 3m/s and the lion simultaneously begins to accelerate at 2m/s . a. How long in seconds it takes the lion to catch up with the hyena? b. How far in meters has the hyena traveled when the lion catches up with it?arrow_forward
