Question

A wedding ring is dropped from a tall building, the distance it has fallen in feet is given by 16t^2, where t is the time in seconds since the ring was dropped. How far has the ring fallen after 2 seconds?

Answer 1

64

Explanation:

As given, the diatance at any point after t seconds is given by

s(t)=16t²

At t=2 seconds then

s(2)=16*2²=16*4=64

Since we're not given the units, it may be feet, inches, meters, kilometers, miles etc. Therefore, the diatance is equal to 64 units
