A plane flying at 78.2 m/s [W32°S] takes 42 seconds to change its velocity to 78.2 m/s
[S32°E].
a) Solve for the change in velocity of the plane algebraically, resolving vectors into their x- and
y-components.
b) What was the average acceleration of the plane over this time interval?
c) Explain why the speed of the plane didn't change and yet the plane underwent
acceleration.
Please label sketches with events as well as GRASS and explanations to show your work. Please
label triangle sides. Remember to have the magnitude rounded to a reasonable number of sig

A cannonball is fired with a velocity of 252 kmph at an angle of 60 degrees. The cannonball lands in a valley 150 metres below its starting level. What is the range of the cannonball?
Make a simple sketch. Make a list of all given values, units, and the variables they represent. write the general form of the equation you are going to use. Insert the known values and solve. State at the start of the problem which direction is positive by using an up or down arrow. Keep the velocity components and time to 2 decimal places.
NOTE: at the end of each question please give proper directions in your final answers.
Here is what you got to know first : For airplanes Vplane + Vwind = VRESULTANT So generally, a subtraction problem will be created if you provide the resultant velocity and either the plane or wind velocities. The person solving the problem will have to use subtraction of vectors to solve for the missing velocity.
An airplane flies with an airspeed of 50.0 m/s [E 40° N]. If the velocity of the airplane, according to an observer on the ground, is 30.0 m/s [SE], what is the wind velocity?
