4. A ball is shot from a cannon at 50 m/s at an angle of 30° above the horizontal. a. Draw a labeled diagram with all relevant information. Note directions you chose to be +x and +y. b. How far has the ball traveled horizontally when it reaches its highest point in the flight? How high is it at this point? c. What is the speed of the ball at the highest point in its flight?

Pls solve this question quickly and 100% correct. Also could you do it handwritten for me to better understand thank you. A small airplane starts flying at a constant speed of 281 km/h on a heading of N79W. A 68 km/h wind is blowing from N13E. Determine the ground velocity of the airplane. Give direction as a quadrant bearing. Include diagram showing the vector addition with your solution.

What is the direction of the acceleration vector for each of these situations? Remember that if an object speeds up, then the velocity and acceleration vectors are in the same direction; if an object slows down, then they are in opposite directions. Any object that is traveling in a vertical direction also experiences acceleration due to gravity. a. {up/ down/ right/ left} Object travels to left and slows down. b. {up/ down/ right/ left} Object is tossed upward.

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.

Please help with parts g and h Two velocity vectors are defined as follows: v1 = 40.0 m/s, 50.0 degrees cw from the +x axis  v2 = 30.0 m/s, 75.0degrees cw from the -y axis     d) Calculate the x- and y-components of v2. Write the vector v2 in terms of its components using unit vector notation.     e) Calculate the x- and y-components of the change in velocity defined as Δv= v2-v1. Write the vector Δv in terms of its components using unit vector notation.     f) Sketch the vector Δv on an x-y grid. Define a relevant angle symbolically whose numerical value you will calculate in the next part.   g) Calculate the magnitude and direction of the vector Δv.   h) Finally, write the vector Δv in terms of its magnitude and direction.
