On the first day, you travel 5.0 km heading East. On the second day you’ve enjoyed the scenery so much that you forgot to take note how far you have walked and in what direction. On the third day, after wandering for 8.5 km and in the direction 37o South of West, you find yourself in the base camp where you have started (which means the total displacement is zero). Determine your displacement during the second day of your trip.
- #3) Use the figure for projectile motion. You are working on your jump shot. The magnitude of the initial velocity for the ball is vo = 9.5 m/s and the angle you launch it is at 37.0°. Note the ball's initial starting height is h = 1.90 m. Most of your points will come from setting up the equations correctly and your algebra manipulation prior to plugging in numbers. Numbers last.

(B) Find the maximum horizontal distance the person can throw ball given these conditions.The pronghorn antelope, found in North America, is the best long distance runner among mammals. It has been observed to travel at Ana everage speed of more than 55km/hr over a distance of 6.0 km. Suppose the antelope runs a distance of 5.0 km in a direction 11.5 degrees north of east, turns, and then runs 1.0 km south. Calculate the resultant displacement.1. A man walks 1.80 km north and then 2.00 km west, all in 3.40 hours. (a) What is the magnitude (in km) and direction (in degrees north of west) of his displacement during the given time?
