Answer: Initial velocity (u) = 49 m/s

Let the time taken to reach the maximum height be t.

Acceleration due to gravity = - 9.8 m/s^2

Final velocity = 0 m/s

Now, using first equation of motion:

0 = 49 - 9.8 × t

t = 5 seconds

Now, we need to find the velocity just 1 second before reaching the highest point.

Hence, time = 4 seconds

Hence, the velocity just 1 second before reaching the highest point is 9.8 m/s.
