In which of the following elevator situations would the acceleration be positive. Select TWO answers

1. moving down at constant speed

2. moving up and slowing down

3. moving up at constant speed

4. moving down and slowing down

5. moving up and speeding up

6. moving down and speeding up

Both options 5 and 6

Explanation:

Let us consider option 5,

In option 5 body is moving up with initial velocity lower than that of final velocity which gets accelerated. Therefore the acceleration is positive in this case.

Let us consider option 6,

In option 6 body is moving down with initial velocity lower than that of final velocity which gets accelerated. Therefore the acceleration is positive in this case.
