You can use dimensional analysis to solve this problem.
( 60 meters / second ) x ( 3.28 feet / 1 meter )
= 196.8 feet per second
You can also use a proportion.
Since 1 meter = 3.28 feet, then 60 meters = x feet.
1 meter / 3.28 feet = 60 meters / x feet
You will get the same answer = 196.8 feet per second.
Acceleration due to gravity is 9.8m/s^2
Time covered = 60/9.8 seconds
Distance covered = 60 x 60/9.8 meters
1 Foot = 0.3048 meters
Distance in foot = 3600/(9.8 x 0.3048) feet
Speed in feet = Distance/ time = 3600/(9.8 x 0.3048) divide by 60/9.8 seconds
Speed in feet = 60/0.3048 = 196.8504 feet/second (to four decimal places)
