TEST FORM-A1) Which of the following graphs represent an object having zero acceleration?A) only graph aB) only graph bC) graphs b and cD) graphs c and dE) 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 itsdisplacement.
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 anddirection 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?AtA) 50 m/sB) 15 m/sC) 375 m/sD) 30 m/s
