A plane is flying South with speed of 900 km/h. At a specific movement the wind start blowing West with speed of 50 km/h. A. Make a representation of the plan with its speed and the speed of the wind. B. Determine the resultant velocity acting on the plane. (Please explain)

1. In a practice session, Iris hits a ball horizontally with a speed of 36 m/s from a height of 3.1 m. The ball travels until it hits the ground. a. Determine the time the ball is in the air. b. Determine the horizontal distance traveled by the ball. c. Calculate the ball’s velocity as it hits the ground.

While playing “Angry Bird”, Red was shot with an initial speed of 17 m/s at an angle 20° abovethe horizontal. The bird moves along parabolic trajectory until it reaches its target. a. Calculate the time needed by Red in the air.b. Deduce the time taken by Red to reach the highest point.c. Calculate the range of Red.d. Calculate the x and y components of the final velocity of Red.e. Deduce its final speed .

4. Swims across Lake Erie are officially sanctioned by the Lake Erie Open Water Swimming Association. Your friend on the swim team wants to swim across the lake. The plan is that your friend will swim to Presque Isle starting at a location at Long Point, Ontario which is 24 miles due north of Presque Isle. You will be navigating a boat with a GPS. Your friend can maintain a speed of 1.80 mph in still water. All during the swim you observe that objects drifting in the water are moving at 0.70 mph to the east due to the current. a. What bearing should you maintain? That is what direction should you point the boat to reach Presque Isle? Give your answer relative to a compass direction (i.e., 30° north of west). Hint, you want your net velocity vector to be straight south. b. How long did it take your friend to swim across Lake Erie? c. What is the addition amount of time that your friend will need to swim compared to if there was no current (assume your friend swims at a constant rate)?

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?

A projectile is fired with an initial speed of 36.6 m/s at an angle of 44.0 degrees above the horizontal on a long flat firing range. C.Determine the total horizontal distance covered (that is, the range). D.Determine the speed of the projectile 1.10 ss after firing.

Part A 1. A plane is heading due cast. Will its ground speed be greater than or less than its airspeed, and will its flight path be north or south of east when the wind is from a. N b. S 80° W c. S 30° E d. N 80° E

Q2. A plane has an airspeed of 915 km/h. The pilot sets the heading at [S34°E]. There is an 84 km/h wind headed [W12°N]. [A7, C4] a) Draw and label the vector diagram for the wind and plane's velocities. b) Calculate the velocity of the plane as seen by an observer on the ground.

Whale sharks swim forward while ascending or descending. They swim along a straight-line path at a shallow angle as they move from the surface to deep water or from the depths to the surface. In one recorded dive, a shark started 50 m below the surface and swam at 0.85 m/s along a path tipped at a 13° angle above the horizontal until reaching the surface. a. What was the horizontal distance between the shark's starting and ending positions?

A commercial jet sets its speed to 525 mph, and points its nose in the direction of 15 degrees west of north (-105 degrees from +x-axis).  However, a strong jet stream is blowing at 110 mph at a direction of 20 degrees.  The actual resultant velocity of the aircraft is the sum of these two vectors. a.  Find the final velocity b. For this airspeed and wind velocity, find the angle west of due north that the nose will need to point in order for the final velocity to be due north.
