Question
Which of the following is true about the graph given below?
- It has a negative slope
- The body has a negative acceleration
- The body is undergoing a uniformly decelerated motion
- All of the above
Hint:
All of the above
The correct answer is: All of the above
Rhe slope is negative (it's in the negative direction), the body has negative acceleration ( the body is slowing down ), and the body is undergoing a uniform decelerated motion ( as the body is decreasing with equal velocity at equal interval of time).
