Problem 19Q

Can an object have zero velocity and nonzero acceleration at the same time? Give examples.

Step-by-Step Solution:
Step 1 of 3

Solution 19Q

The car in the picture has started to move from rest with an acceleration of a. Just at the moment of start its speed is zero but acceleration is a. If the only force acting on an object is its weight the object is said to be falling freely. All freely falling objects experience the same gravitational acceleration of g=9.8m/s2. The object in the figure thrown upward with a velocity of  V0, it reaches the highest point and turn back to ground. All along the motion its acceleration is the same, gravitational acceleration of g=10m/s2. When this  object is at highest point of its flight, the speed is zero but still it has the gravitational acceleration of g=10m/s2.
