QUESTION 12 A rest observer is measuring the velocity of an object that is moving with a constant acceleration In 1D. At t1=0 s, the observer measures velocity of the object is 18 m/s. At t2-12 s, the observer measures velocity of the object is 97 m/s. what is the distance not required to include the unit in your answer)? (Note: For fill in blank, I have set the unit for the answer. So, you just need to provide a number - Please write your numerical answer with all digits and do not use scientific notation. If you are not sure about the number of significant figures, you can keep the number of figures as many as possible – You will not be punished for doing this.) m of the object that has moved from time t1 to t2 (In the unit of m, you are QUESTION 13 A bicyclist starts a timed race at 6.0 mi/h. In order to win, he must average 21 mi/h. Assuming constant acceleration from the start, how fast must he be traveling at the end of the race? OA 24 mi/h Save and Submit to save and submit.…

Figure below is a velocity-versus-time graph for a moving object. The object starts at position x = 0. What is the acceleration at t= 1.0 s, in m/s2? Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. time in seconds

For God sake this is third time I post it all the time the given answer was wrong and was chat gpt answer that I have no need . Plz give Correct solution and correct graph i definitely upvote for your solution. Please plz please please.

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
