A treasure hunter follows a map moving 25 km [N], 37 km [W 37 degrees S], 63 km [E 65 degrees S] and finally 15 km [N 17 degrees E]. If his average for the entire trip was 45 km/hr, calculate: a. The total time for the trip; and b. The average velocity of the trip

During 9.67 s, a motorcyclist changes his velocity from v1,x = -39.1 m/s and v1,y = 13.7 m/s to v2,x = -23.7 m/s and v2.y = 29.9 m/s. Find the components of the motorcycle's average acceleration during this process, a,v,x and av.y. Aav,x m/s? dav,y m/s? II

A student drove to the university from her home and noted that the odometer reading of her car increased by 12.0 km. The trip took 17.9 min. a.If the straight-line distance from her home to the university is 10.310.3 km in a direction 28.028.0º south of east, what was her average velocity? (magnitude and direction south of east) b.If she returned home by the same path 6.50h after she left, what was her average speed for the entire trip?

A miniature quadcopter is located at xi= 2.00 m and yi = 4.50 m at t = 0 and moves with an average velocity having components vave, x = 1.50 m/s and vave, y = -1.00 m/s. What are the x-coordinate at time t = 2.00 s? _ m y-coordinate at time t = 2.00 s?_ m

A soccer ball is kicked from the ground with an initial speed of 18.9 m/s at an upward angle of 48.1. A player 48.4 m away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground? Neglect air resistance.Use g-9.81 m/s². Number 4.32 Unit m/s

A cart is propelled over an its greatest y coordinate? xy plane with acceleration components a, = 6.8 m/s? and a, = -1.5 m/s2. Its initial velocity has components Vox = 7.3 m/s and voy = 12.4 m/s. In unit-vector notation, what is the velocity of the cart when it reaches Number Units

A sailor is enjoying a nice day on his sailboat, sailing west with the wind at constant velocity. At one point the sailor spots an anchored buoy some distance to the east of the boat, and turns on his motor to head towards it. The boat kept gliding to the west for some distance before turning around and heading eastward. The boat was traveling initially with velocity v = -6.0i m/s and it took the the boat 2.0 s to turn around. What is the velocity of the boat, 5.0 s after the motor is turned on? The coordinate system is set up such that the +i direction is East. Pick the correct answer O +3.0î m/s O -9.0i m/s O -3.0î m/s o +9.0å m/s o +2.0i m/s
