Do 9. turns around to backtrack to a missed exit and travels directly southbound for 7 miles Do the following: 8. Car 1 exits a rest stop and travels northbound on a highway for 25 miles. Car 1 then Draw position vectors for Car I's northbound position and Car I's southbound position. Draw the change in position vector (displacement) of Car I's journey. a) b) 9. Squirrel sitting on a deck railing starts running along a straight line over a...
1. A car travels 30 miles north, then 10 miles east. The displacement vector is X miles north, Y miles east. A) What is X? B) What is Y? 2. A car travels 30 miles north, then 10 miles east, then 20 miles west, then 2 miles south. The displacement vector is X miles north, Y miles east. A) What is X? B) What is Y? (beware of signs) 3. A car travels 30 miles northwest. The displacement vector is...
A car travels East at a constant velocity of 83 km/hr relative to the ground. A truck travels West at a constant velocity of 51 km/hr relative to the ground. What is the velocity of the truck relative to the car (enter the magnitude and direction separately)? Before you do any calculations, make sure that you draw a diagram that shows reference frames S and S'. Also, make sure that you label the velocities u, u', and v in your...
Part 2 (Choose 3 Nom TUTT I 1. A race car starts from rest and travels 400 meters in 5.2 seconds. When it crosses the finish line it has a final velocity of 140 m/s. a) What is the acceleration (a) of this car? b) How much time was spent traveling from 100 m/s to 140 m/s? c) If this car continued at this rate of acceleration, how long would it take for it to travel 800 meters? 2. A...
7. Do the projectile motion General Motion with Unit Vectors and Components An object undergoes the following consecutive displacements: s (2i +3j +5k)m,s2 (6i- 9j + 2k)m, and s3 (10i 8j -k)m. a) Find the resultant displacement in terms of unit vectors and components. b) State the magnitude of the resultant displacement. 2. Suppose a hiker travels 5 km southwest from their camp. Then, the hiker travels 2 km 75° north of east. a) Find the displacement of the hiker...
Please try to answer all questions and show work. Thank you. 1. A baseball player is warming up and tosses a ball straight up into the air. The ball travels up until it reaches some maximum height, and then falls back down to the player's hand. If we neglect air resistance, then the magnitude of the acceleration of the ball is? A. largest the moment after it leaves the players hand. B. smallgst the moment after it leaves the player's...
