It is known that the distance in metres through which a body falls freely varies directly as the square of the time taken. If a
body falls through 80 metres in 4 seconds, find the distance it would fall in 5 seconds.
1 answer:
Answer:
125 meters
Step-by-step explanation:
Let distance = d and time is t
Using the variation;
d = k t^2
So let’s us get k
80 = k * 4*2
16k = 80
k = 80/16 = 5
So for 5 seconds, the distance would be;
d = 5 * 5^2
d = 125 meters
