Unreasonable Results A cyclist rides 16.0 km east, then 8.0 km west, then 8.0 km east, then 32.0 km west, and finally 11.2 km east. If his average velocity is 24 km/h, how long did it take him to complete the trip? Is this a reasonable time?

Super Joe, using his incredible Physics knowledge, starts from rest and accelerates at a spectacular rate of 12.0 m/s? for a distance of 375 m. He then uses his awesome powers to slow down at the rate of -7.50 m/s? until he comes to rest. (a) What is the total distance traveled by Super Joe? (b) How long was Super Joe in motion, from start to stop?

A car racing in a 420m drag race starts from rest and accelerates uniformly to 34.0m/s in the first 1.70s, and then continues at this speed to the finish line. How far does the car travel during the initial acceleration period and how much total time is required by the car to finish the race?

QuesuvI Z VETJ Points: 2 Kim is waiting for the results of her physics exam. She walks 8.0 metres north in 5.0 seconds, then 25 metres south in 15.0 seconds, then 10.0 metres north in 10.0 seconds. Use this information to answer the following questions: (1) What is Kim's average speed? (ii) What is Kim's average velocity? DA) Kim's speed is 1.4 m/s B) Kim's speed is 0.23 m/s C) Kim's speed is -0.23 m/s D) Kim's speed is -1.4 m/s E) Kim's velocity is 1.4 m/s [N] F) Kim's velocity is 0.23 m/s [S] G) Kim's velocity is 0.23 m/s [N] ⒸH) Kim's velocity is 1 4 m/s [S] Clear selection Question 3 of 13

A motorcycle officer hidden at an intersection observes a car driven by an oblivious driver who ignores a stop sign and continues through the intersection at a constant speed. The police officer takes off in pursuit 2.0s after the car has passed the stop sign. She accelerates at 4.2 m/s^2 until her speed is 110 km/h until she catches the car. The car is 1.4 km from the intersection. a) How long did it take for the officer to catch the car? b) How fast was the car traveling?

You get in your car and drive north, accelerating up to 60mph. Draw your velocity vector and acceleration vector some time during your acceleration. How would these change if you encountered traffic and started to brake?

A speeding driver noticed a police car parked about 433 m in from of him on the side of the road and reduced his speed at a constant rate for a duration of 10.7 seconds as he drove past the police car, at the legal speed of 33 m/s. What was the car's acceleration (include a negative sign in your answer)?
