Question

a water tank is placed on top of a building of height 19 . water overflowing from the tank was found to reach the ground in 2 seconds . find the height of the tank .(take g= 10ms'1

Answer 1

S=ut+1/2g*t*t
Total distance = 19 + x
X is height of tank
19+x=1/2*10*2*2
X=1m

Answer 2

Answer:

1m

Explanation:

h = ut + ½ gt^2

19 + x = 0 x 2 + ½  x 10 x 2 x 2

19 + x = 0 + 20

x = 20 - 19

x = 1 m
