The final speed of the object is 15.3 m/s
Explanation:
The object in the problem is moving by uniformly accelerated motion (it is in free fall), so we can use the following suvat equation:
where
v is the final velocity
u is the initial velocity
is the acceleration of gravity (taking downward as positive direction)
s is the vertical displacement
For the object in this problem:
u = 0 (it starts from rest)
s = 12 m is the displacement of the object
Solving for v,

The fastest pitch ever thrown was 105 MPH. Hope this helps!
Answer:
after t = 3 hours compound A remain 0.396 M
t = 12.98 hours
Explanation:
P = P_0*e^(-kt)
t = 30 minutes = 30/60 hours = 0.5 hours
and P_0 = 0.60M
and P after t = 0.5 hours is 0.56 M
(0.56/0.6) = e^(-kt)
0.933 =e^(-kt)
k = 0.138
P = P_0*e^(-0.138t)
Now after t = 3 hours,
P = 0.6* e^((-0.138)*3) = 0.396 M
time when P = 0.1 M
0.1 = 0.6*e^(-0.138t)
t = 12.98 hours
Answer:
10 159.8744 m
Explanation:
Hi there!
Since
<em> 1 mile = 1609.34 m</em>
and:
<em> 1 yard = 0.9144 m</em>
We have that:
<em>6 miles + 551 yards = 6 *(1609.34) + 551*(0.9144) m</em>
Therefore, the distance is (in meters):
d = 10 159.8744 m
Rounded to the first decimal
d = 10 159.9 m
