An object has a positive positon and a negative acceleration. Which statement is describing its motion correct?
a) It is speeding up
b) It is slowing down
c) It is stationary
d) There is not enough information to describe its motion
An object has a positive position and a negative acceleration. Here position is always defined as relative to another object or position. For example once you sit in bus and bus moves .Here relative to bus you are stationary i.e not moving but at same time relative to road you are moving because in moving bus your position is changing every moment of time with respect to road but your position with respect to bus remain same or unchanged. So position is negative or positive it will not describe motion. A negative acceleration or retardation means your current velocity is less than the velocity just before . It means you are slowing down.
Correct choice is b : It is slowing down
