Whats the main difference between distance and displacements. Choose all that apply. 1. distance is a vector and displacement is a scalar 2. distance is how far and displacement is how far in which direction 3. Displacement is defined by magnitude and direction both but distance is defined by magnitude only 4. displacement is calculated by how far the object travels without paying attention to the direction of travel, and distance is calculated by the change in position it the object 5.displacement is calculated by Calcutating the change in position of the object and distance is calculated by how far the object traveled without paying attention to the direction of travel. 6. displacement is a vector and distance is a scalar.
I need help on this question. Could you please draw a diagram. Could you also explain how your answers are reasonable and explain whether the answers are reasonable relative to the context provided in the question?

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 figs, the unit and the direction (if needed) in your answers.

5. A basketball is thrown from the roof of the school building as part of a science experiment examining gravity. The basketball is thrown from 25 feet above the ground at an initial velocity of 40 feet per second and at an angle of elevation of 30°. Write a set of parametric equations that model the basketball's horizontal and vertical position. 6. The basketball reaches its maximum height at t 0.625 seconds. Using your parametric equations from part 5, determine the location of the basketball at its maximum height relative to the starting point. %3D

2. The position of a drone as a function of time is given by *(t) = ( 8 i + 1.5 k) + (-3 î + 2 j) t – 0.5 t2 j The units are missing in the constant coefficients above, i.e., "0.5" should be "0.5 m/s2". Include the correct units on all the constant coefficients in your answers below. a. What is the x-position of the drone as a function of time? b. What is the y-position of the drone as a function of time? c. How far away is the drone from its starting position at t = 3s? d. What is the acceleration vector? е. What is the velocity vector as a function of time? (One way to do this is to take the time derivative of the position vector.) f. Make a sketch of the x, y, and z positions of the drone as function of time. You just need the general shape. time time time
