PHYSICS 8 [MIDTERM EXAM] A) 6.9 N D) 4.7 N starting point and point P, the B) 7.2N C) 2.8 N 22) A cyclist follows the track shown below. While moving between the sthular path eyelist acquires a maximum speed v which she maintains constant around t points P and Q. he circular path defined by Which vector best represents the direction of average velocity between points P and QZ Circle the answer and show your reasoning behind your choice(s) A) B) D) E) 0 23) Refer to the same figure above. Which vector best represents the direction of average accele between points P and Q?Explanation / Answer
In case of velocity, the vector is always tangent to the circular track. Magnitude is same but direction is constantly changing. Therefore average velcoity should point up. It means correct answer should be (A).
In case of acceleration, the vector always points towards the center no matter the position. Therefore, the average acceleration vector should point to the left. from given choices answer should be (D)
