Answer:
0.447 sec
Explanation:
velocity = distance/ time
distance 'h' is a function of time 't' given by
⇒ differentiating equation
⇒ velocity =
⇒ acceleration = = 24
deceleration due to gravity = -9.8 m/ = - 9.8 x 3.281 = - 32.154 ft/
Net deceleration = 24 - 32.154 = - 8.15 ft/
at maximum height v = 0
=
+ 2ah
⇒ 0 = + 2 (-8.15)h
⇒ h = 118.72 ft⇒
118.72 = 12 + 44t + 16
⇒ - 102.72 = 0
⇒ t = -44 ± / (2 x 12)
t = 0.447 sec
Answer: B . Merchants' understanding of the patterns of the monsoon winds
Explanation:
India faces a very heavy monsoon every year that brings heavy rainfall and very strong winds.
It would make sense that for merchants to have been able to trade in India in the past, they would have had to have a good understanding of the patterns of the monsoon winds so that they would embark on their trade missions with little to no losses.
