Answer:
Explanation:
Given
Width of river=200 m
Speed of river=2 m/s
Speed of Boat relative to river=8 m/s
Boat leaves the bank west of north
Therefore velocity of boat w.r.t ground
Magnitude of boat speed
For direction
w.r.t to west
to cross the river its north component will help so
time taken
D cause u can measure how powerful that wave was
<span>An equivalent simple pendulum is of period equal to that of the corresponding compound pendulum.</span>
The large can of solids will reach before the empty can reason being is it has more additional weight its like dropping a 1 pound weight compared to a 4 pound the 4 pound reaches faster because of the gravitational pull the size of the pull depends on the masses of the objects
Formula for stopping distance can be calculated by
here
now we can see from above equation that stopping distance depends on square of the speed.
So as we can see that here 30 mph and 60 mph, if the speed is double then the stopping distance will become four times more.
