A pilot is in his plane with the intention of flying to Nunavut. From the current location, Nunavut is [N 9.0W]. The flight tracker estimates the distance from Toronto to Nunavut is approximate 3.0x103km. The plane hasthe capability to fly at an airspeed of 890 km/hr. The pilot aims the plane at a heading [N], and lands in Nunavutdirectly. If the flight takes 3.33 hrs to complete: a. What is the velocity of the plane relative to the Earth? b. What was the wind velocity present on that day?
Two cars approach each other at an intersection. Car A is traveling south at 30 m/s, while car B is traveling 70 degrees north of east at 50 m/s. What is the speed (in m/s) of car A as seen by the driver of car B?
A plane is headed due west with an air speed of 207 m/s. The wind blows south at 20.0 m/s. Find the velocity of the plane relative to the earth.To solve this problem it will be necessary to determine the plane's velocity relative to the the air. What is the plane's east-west velocity relative to the air? (Define the positive direction to be east.)Additionally, to solve this problem it will be necessary to determine the air's velocity relative to the earth. What is the air's north-south velocity relative to the earth? (Define the positive direction to be north.)

While scavenging for acorns before the big winter, Scrat the Squirrel leaves his tree house and skitters along 8.00 m at a heading of 40.0° SoE to collect two acorns. Then, he traipses off 10.0 m West to snag another acorn. Finally, he sees a big prize and hurriedly rushes 12.0 m at 20.0° EoN. If he must now make it back to his tree house, how far and in what direction should he head to go home? I know the answer I just don’t know how to get it. Answer: 6.14 m @ 87.8° NoE Thanks!!
