Answer:
T = 1.5s
Step-by-step explanation:
Hello,
To find the time the pincone hits the ground, we need to use the equation given.
Note that h = 0 when the pinecones hits the ground.
This question relates to motion under gravity.
h = -16t² + 36
0 = -16t² + 36
Make t² the subject of formula
16t² = 36
t² = 36 / 16
t² = 2.25
Take the square root of both sides
t = √(2.25)
t = 1.5s
The time it takes the pinecone to hit the ground is 1.5s.
60 seconds in 1 minute.....60 minutes in one hr....60 * 60 = 3600 seconds/hr
110/3600 = x / 2......110 km in 3600 sec = x km in 2 sec
cross multiply because this is a proportion
(3600)(x) = (110)(2)
3600x = 220
x = 220/3600
x = 0.0611 km/hr <==
