Question

Henry Ford College/ Physics 231-71 Winter 2038 3) If the eastward component of vector is equal to the westward component of vector northward components are equal. Which one of the following statements about these two vectors is correct? and their A) vector A is parallel to vector B . 8) Vectors and point in opposite directions c) Vector is perpendicular to vector D) The magnitude of vector is equal to the magnitude of vector E) The magnitude of vector A is twice the magnitude of vector B 4) For general projectile motion, when the projectile is at the highest point of its trajectory A) its acceleration is zero. B) its velocity is perpendicular to the acceleration. C) its velocity and acceleration are both zero. D) the horizontal component of its velocity is zero. E) the horizontal and vertical components of its velocity are zero. 5) The figure represents the velocity of a particle as it travels along the x-axis. At what value (or values of t is the instantaneous acceleration equal to zero? (m/s) A)t=0 B) t = 0.5 s and t = 2 s Winter 2018 Exam 1-Kinematics V Instructor: Eduart Aliko Page 2

Explanation / Answer

3..D) the magnitude of Vector A is equal to vector B.

4.B) its velocity is perpendicular to acceleration

5.instantaneous acceleration will be zero when slope will be zero.

so c) t =1 second
