The coordinate system given below is measured in units of blocks. cafeteria dorm physics library 0 2 3 x (blocks) 7Cafeteria 7 physics a. What is the position of the physics building with reference to the dorm? Also include the direction of the physics building in your answer. b. What is the position of the cafeteria with reference to the dorm? Also include the direction of the cafeteria in your answer. c. What is the position of the library with reference to the cafeteria? Also include the direction of the library in your answer.A motorcycle begins at rest at t0 = 0 seconds. The motorcycle starts moving, and eventually covers a distance d = 840 m, in a time tf = 189 s. In a coordinate system with north being the positive x-direction, the motorcycle's motion is in the northern direction (see figure). 1. What was the motorcycle's average velocity in in the northern direction vavg,N, in this period in meters per second? 2. If the motorcycle's final velocity at tf was 12 m/s, what was the motorcycle's average acceleration in the northern direction, aavg,N, during this period in m/s2?A GPS shows that my friend’s house is 10.0 kmkm away, as shown in the image below. But there is a big hill between my houses and I don’t want to bike there directly. I know my friend’s street is 6.0 kmkm north of my street. How far do I have to ride before turning north to get to my friend’s house?

- David is buying a jet boat this summer and spending a lot of time zooming around. One place he plans on going is to the Plate River above Albany, NY. The current is 4 m/s south and the river is 200m wide. the boat will move at 20 m/s at full throttle, his only setting. A. how quickly will he cross the river if he heads straight across?B. how far downstream will he end up if he does so?C. if he wants to go straight across, what angle upstream should he use?Pls solve this question quickly and 100% correct. Also could you do it handwritten for me to better understand thank you. A small airplane starts flying at a constant speed of 281 km/h on a heading of N79W. A 68 km/h wind is blowing from N13E. Determine the ground velocity of the airplane. Give direction as a quadrant bearing. Include diagram showing the vector addition with your solution.What is the direction of the acceleration vector for each of these situations? Remember that if an object speeds up, then the velocity and acceleration vectors are in the same direction; if an object slows down, then they are in opposite directions. Any object that is traveling in a vertical direction also experiences acceleration due to gravity. a. {up/ down/ right/ left} Object travels to left and slows down. b. {up/ down/ right/ left} Object is tossed upward.
