- 5) A roller coaster moves 200 m horizontally and then travels 135 m at an angle of 30.0 degrees above the horizontal. It next travels 135 m at an angle of 40.0 degrees below the horizontal. What is its displacement from its starting position? (421 m @ -2.63 degrees)an airplane climbing at an angle of 45 degrees passes directly over a ground radar station at an altitude of 1 mile. a later reading shows that the distance from the radar station to the plane is 5 miles and is increasing at 7 mi/h. what is the speed of the plane in mi/h3. Find the total distance traveled and displacement for each set of directions. Explain your directions using a component chart Directions 1: 4 km due east 3 km due south 10 km due west 5 km due north 4 km due west 2 km due north Directions 2: 7 km due west 2 km due north 10 km due east 6 km due south 7 km due east 12 km due north.
- 4. The mouse continued its trek and headed rightward (+x) for 100 cm. Update the graph, and calculate the magnitude and direction of the mouse's displacement.3)A toy airplane flies clockwise at a constant speed in a horizontal circle of radius 8.0 meters. The magnitude of the acceleration of the airplane is 25 meters per second squared. The diagram shows the path of the airplane as it travels around the circle. What is the speed of the plane?I) (a) We will start with displacement, the straight line (as the crow or airplane flies distance) covered by a moving object starting from an initial location and arriving at a final location. Vector quantities will be written in bold face i.e. A. Consider the situation of an ant that travels east, i.e. along the x axis, for 8 cm then travels northeast, i.e. 45° from the x axis, for 11 cm. Represent each leg of this journey by a vector on your graph paper. Vectors are written as arrows with the direction going from the tail of the arrow to the head of the arrow and the length of the arrow proportional to the magnitude (size) of the vector. Indicate the first part of the journey by an arrow of length 8 cm whose tail starts at the origin of your graph and whose head is at 8 units along the positive x direction. Call this vector A which is the displacement of the first part of the ant's journey. Now starting at the head of A draw a vector B which represents the second part of the ant's…
- Physics Question: Two bicyclists , starting at the same place , are riding toward the same campground by two different routes. One cyclist rides 1080 m due east and then turns due north and travels another 1430 m before reaching the campground. The second cyclist starts out by heading due north for 1950 m and then turns and heads directly toward the campground. (a) At the turning point , how far is the second cyclist from the campground ? (b) In what direction (measured relative to due east) must the second cyclist head during the last part of the trip ?a) What is the average speed in kilometers per second of the Earth around the sun, given that the radius of the Earth's orbit is 1.5×108km? b) What is the average velocity of the Earth over a year's time?Suppose a rocks falls vertically off of a 1500 foot cliff. Use the distance equation for an object in free fall, , to determine the rock's distance from the ground, in feet, after 2 seconds of free fall.
- A girl delivering newspapers covers her route by traveling 1.75 blocks west, 3.75 blocks north, and then 6.75 blocks east.What her resultant displacement? - magnitude - direction (north of east)A swimmer wants to cross a river that is flowing east at 0.95 m/s . To do so, the swimmer points 33.0o north of west. How fast must they swim relative to the water so that they swim directly north across the river? Give your answer in meters per second to two decimal places1) A student drove to the university from her home and noted that the odometer reading of her car increased by 15.8 km. The trip took 25.9 min. a) What was her average speed, in meters per second? b) If the straight-line distance from her home to the university is 10.3 km in a direction 25° south of east, what was the magnitude of her average velocity in meters per second? c) If she drove back home using the same path she took out to the university and arrives 7.9 h after she first left home, what was her average speed for the entire trip, in meters per second?
