Answer:
Explanation:
Conceptual analysis
We apply the kinematic formula for an object that moves vertically upwards:
Where:
: final speed in ft/s
: initial speed in ft/s
g: acceleration due to gravity in ft/s²
y: vertical position at any time in ft
Known data
For 
,
; where h is the maximum height
for y=h, 
Problem development
We replace , 
in the formula (1),
[
Equation (1)
in maximum height(h): , Then we replace in formula (1):
Equation(2)
We replace (h) of Equation(2) in the Equation (1) :
Answer = C
It blows towards the poles from the sub-tropical high pressure areas
neutral objects is correct
Answer:
91.84 m/s²
Explanation:
velocity, v = 600 m/s
acceleration, a = 4 g = 4 x 9.8 = 39.2 m/s^2
Let the radius of the loop is r.
he experiences a centripetal force.
centripetal acceleration,
a = v² / r
39.2 x r = 600 x 600
r = 3600 / 39.2
r = 91.84 m/s²
Thus, the radius of the loop is 91.84 m/s².
