I'm pretty sure it is coal
hope this helps!
Answer:
x = 2.26 miles from the shore P i.e. point at which boat be landed.
Explanation:
x is the distance from point of landing i.e R and P
So, she cover a distance miles
She rows with a speed of 3 miles per hour.
So, time taken for rowing
She walks a distance = RQ = 14-x
She walks with a speed of 4 miles per hour.
So, time taken by the woman for walking \
Thus, total time taken
For total time to be least, T ' = 0
T '
x = 2.26 miles from the shore P
Answer: 1.76 s
Explanation:
We have the following data:
is the total mass of the bike and the rider
is the initial velocity
is the force applied to the brakes
Firstly, we will find the acceleration with the following equation:
(1)
Isolating :
(2)
(3)
(4) This is the magnitude of the acceleration, however, since the final velocity is 0 m/s, this means the direction is negative
Hence:
(5)
On the other hand, with the following equation we can find the time :
(6)
Where:
is the final velocity (the bike stops)
Isolating :
(7)
(8)
Finally:
This iste time it takes to the bike to stop
