A police officer is driving due north at a constant speed of 28 m/s relative to the ground when she notices a truck on an east-west highway ahead of her, traveling west at high speed. She finds that the truck's speed relative to her car is 41 m/s (about 92 mph). On a sheet of paper, sketch the vector triangle that shows how the truck's velocity relative to the ground is related to the police car's velocity relative to the ground and to the truck's velocity relative to the police car. The sketch need not be to scale, but the velocity vectors should be oriented correctly and bear the appropriate labels. What is the truck's speed, relative to the ground? Number i Units +

Consider the game of baseball. A pitcher throws a ball to the catcher, with a speed of 86 miles per hour (38.45 m/s). If the velocity of the ball is horizontal when it leaves the pitcher's hand, how far (vertically) will it fall on the way to the catcher? The distance from the pitcher to the catcher is 57 feet (the pitching distance used from 1890 to 1893). Express your answer in meters and feet. m ft

I have no idea to how to start to this question: Wags (a dog) decides to go on a journey. He begins his journey by traveling 58 meters in a direction directly south. He then runs 100.0 meters in a direction 30◦north of west. During the last leg of his journey, he follows a scent for 59 meters in a direction 30◦east of north. What distance does Wags end up from his initial startingpoint?
A person walks in the following pattern: 3.1 km north, then 2.4 km west, and finally 5.2 km south. (a) Sketch the vector diagram that represents this motion. (b) How far and (c) in what direction would a bird fly in a straight line from the same starting point to the same final point?
A police officer is driving due north at a constant speed of 26 m/s relative to the ground when she notices a truck on an east-west highway ahead of her, traveling west at high speed. She finds that the truck's speed relative to her car is 56 m/s (about 130 mph). On a sheet of paper, sketch the vector triangle that shows how the truck's velocity relative to the ground is related to the police car's velocity relative to the ground and to the truck's velocity relative to the police car. The sketch need not be to scale, but the velocity vectors should be oriented correctly and bear the appropriate labels. What is the truck's speed, relative to the ground?

The F-35A, one of the U.S. Air Force's latest fifth-generation fighter was taken 160 km away from the terminal with a speed of 30. km/h and released. The F-35A returned back to the terminal after 4 days. If we place the origin at the terminal and extend the +x-axis to the release point. With that, what is the distance traveled by the F-35A for the entire trip, the F-35A’s average speed in m/s for the entire trip, the F-35A’s average velocity in m/s for the return flight, and the F-35A’s average velocity in m/s for the entire trip?
