Answer:
The bird will take 0.88 seconds to reach a height of 40 feet in the air for the first time
Step-by-step explanation:
we have

This is a vertical parabola open downward
The vertex represent a maximum
where
h is the height of the bird
t is the amount of time, in seconds, the bird had been in the air
For h=40 ft
substitute in the quadratic equation



The formula to solve a quadratic equation of the form
is equal to
in this problem we have

so
substitute in the formula
therefore
The bird will take 0.88 seconds to reach a height of 40 feet in the air for the first time
Step-by-step explanation:
Volume is cubed. so it would be 6^3
so 6*6*6 = 216
Answer:
The average force applied to the baseball is 8.25kN
Step-by-step explanation:
This problem bothers on the impulse of a force
We know that the change in momentum is expressed as
Ft= mv-mu
Given
Ft=16.5 kg-ms
Time t of impact =0.00200s
The force applied can be solved for
By making F subject of formula
F= (mv-mu)/t
F=16.5/0.002
F= 8250N
F= 8.25kN

56+35+CB=180
CB=91
AE=117
AEC=180+56=236
BDA=89+56+180=325
