Problem 15E

Cite an instance in which your speed could be zero while your acceleration is nonzero.

Step-by-Step Solution:
Step 1 of 3

ANSWER: Let’s take an example where the speed is decreasing gradually. At the end when the speed reaches the value zero, still it will be accelerating or you can say decelerating more specifically. Because acceleration shows the rate of change of velocity. The decreasing velocities are let’s say, V n V n1,V n2, V n(n1) V 0 The acceleration is, (V n(n1) V )0/ (t f t i----------------(1) The answer will be some non zero number but the velocity would have reached zero already. Here the speed will be zero with non zero acceleration. The example will be, a ball thrown vertically upwards. The moment it’s speed will become zero at the top, it would have an acceleration which is 9.8 m/s . 2
