- Question 20 A helicopter is heading S 43° E (i.e. direction angle of 313°) with an airspeed of 27 mph, and the wind is blowing S 13° E (i.e. direction angle of 283°) at 10 mph. Helicopter's speed Round all numbers in your answers below to 2 places after the decimal point. (a) Find the velocity vector that represents the true heading of the helicopter. Type your answer in component form, (where a and b represent some numbers). Velocity vector of helicopter's true heading: (b) Find the helicopter's speed relative to the ground (in mph). mph (c) Find the helicopter's drift angle, 8. (The drift angle is the number of degrees that the helicopter will end up flying off-course.) 8 = Submit Question degreesHiker Harry walks 4 km east then 7 km 25o north of west. What is the magnitude and direction of Harry’s position after his hike as measured from his starting point? Give the angle measured relative to east.

- Please asapThe horizontal distance or range (R) of an object thrown at an angle θ from the horizontal is represented by the equation below where v0 is the initial velocity as the object leaves the hand, in feet per second. If v0 = 2500 feet per second and θ is changed from 13° to 14°, use differentials to approximate the change in range, in feet.An airplane leaves the runway heading south and flies for 2000km. It then heads 20 degree west to avoid a storm. After flying for 500km, it turns 40 degree toward the east and flies another 400km to its final destination. Calculate the displacement of the plane;s destination and the distance it travelled.
