Answer:

10.38m

Step-by-step explanation:

Using the equation of motion formula

∆S = ut+1/2at²

S2-S1 = ut+1/2gt²

u is the initial velocity

t is the time taken = 2secs

g is the acceleration due to gravity = 9.81m/s²

30-S1= 0(2)+1/2(9.81)2²

30- S1 = 0+4.905(4)

30 -S1 = 19.62

-S1 = 19.62-30

-S1 = -10.38

S1 = 10.38m

The distance closest to how far it should have fallen after 2secs is 10.38m
