Step 1: Calculate the speed after falling 20 m
The person starts from rest, so the initial speed is 0 . We use the formula:
v2‌=u2+2gh
v‌=√2×10×20
v‌=√400=20m∕s
This means after falling 20 meters, the person is moving at 20m∕s.
Step 2: Find the time to fall the first 20 m
Use the formula for distance with constant acceleration from rest:
s‌=ut+‌

20‌=5t2
t2‌=4
t‌=2‌ seconds ‌
So, it takes 2 seconds to fall the first 20 meters.
Step 3: Calculate the distance left after 20 m
The total height is 2000 meters. After falling 20 meters, the remaining distance is:
Remaining distance 2000−20
=1980m
Step 4: Find the time to travel the remaining 1980 m at constant speed
Now, the person moves at 20m∕s (from step 1). Time taken is:

=99‌ seconds ‌
Step 5: Add both times to get the total time to reach the ground
Total time =2+99=101 seconds.
