The answer for this is 5 seconds.

Here's an explanation:

The average acceleration as an object falls in 9.8m/second. The question is asking how long it will take before the acceleration is 49m/second. Since it's 9.8m/second, then you'll have to divide 49 by 9.8 to find the answer. The quotient of this is 5, so that's your answer.
