Answer:
34
Step-by-step explanation:
9 to the 4th power is 6561
8.64E9 = 8640,000,000
8.64E14 = 864,000,000,000,000
8.64E11 = 864,000,000,000
8.64E13 = 86,400,000,000,000
Multiply 7 times 50 and 7 times 6 then add them
ex: [(7 X 50) + (7 X 6)]
The speed in feet per second is 247.5
The parachutist will fall 4950 feet during 20 seconds.
Step-by-step explanation:
Given,
Speed during free fall = 75 meters per second
It is given that,
1 meter = 3.3 feet
75 meter = 75*3.3 = 247.5 feet
Therefore;
Speed during free fall in feet = 247.5 feet per second
Now,
1 second = 247.5 feet
20 seconds = 247.5*20 = 4950 feet
Fall during 20 seconds = 4950 feet
The parachutist will fall 4950 feet during 20 seconds.
