Question
The vt the motion of a particle along a straight line t (s) For each of the following questions, seloct the appropriate answers from the cheices below. E.g.if A and C answer the first question, and B is the answer for the remaining questions,enter ACBBB. If a question has two or more answers, enter them alphabetically; enter N for none Note that at point B, you cannot tell whether the speed is increasing or decreasing. Why?) i. W'hen does the particke have the smallest speed (without stopping)? li. When is the speed of the particle decreasing? ili. When is the iv, When is the velocity less than zero? zero?Explanation / Answer
at point A the particle has smallest speed.
speed of particle decreasing means slope of graph is negative.so answer is AC
acceleration is zero when slope is zero. so answer is D
velocity is less than zero for CDE
