TEST FORM-A 1) Which of the following graphs represent an object having zero acceleration? A) only graph a B) only graph b C) graphs b and c D) graphs c and d E) graphs a and b
2) Which of the following graphs represent an object at rest? (There could be more than one correct choice.)
3) An object moves 15.0 m north and then 5.0 m south. Find both the distance it has traveled and the magnitude of its displacement.
4) A car is traveling north at 20.0 m/s After 12 s its velocity is 14.0 m/s in the same direction. Find the magnitude and direction of the car's average acceleration.
5) A car travels at 20 m/s due east for some time. It then speeds up with a constant acceleration of 2.0 m/s2for 15 s. the end of this time, what is its velocity? At A) 50 m/s B) 15 m/s C) 375 m/s D) 30 m/s
