Answer:
Step-by-step explanation:
3 hours is equivalent to 180 minutes (found by multiplying the number of hours, 3, by the number of minutes in an hour, 60).
Therefore, the fraction of 3 hours that 25 minutes represents is 
, which can further be simplified to .
Answer:
Step-by-step explanation:
the slope is in the equation
-6/7 is the slope
G = (-W+7)²
W = 7 -√G
W -7 = -√G
-W +7 = √G
(-W +7)² = G
<span>a)
Acceleration of stone = 10
Integrate:
So velocity = 10t
Integrate again:
So distance from starting point = 5t^2
Distance from ground = 450-5t^2
b)
450 - 5t^2 = 0
9.48 seconds
c) velocity = 10t
Put the time into this to give:
94.8 m/s
d.
Velocity = 10t + 5
Integrate again:
5t^2 + 5t
Solve
5t^2 + 5t = 450
Gives 9 seconds</span>
