Answer:
Explanation:
The equation for the linear impulse is as follows:
where is impulse,
is the force, and
is the change in time.
The force, according to Newton's second law:
and since
the force will be:
replacing in the equation for impulse:
we see that is canceled, so
And according to the problem ,
and the mass of the passenger is
. Thus:
the magnitude of the linear impulse experienced the passenger is
Answer:
pirate walk 259 feet
displacement vector = 111 i - 234 j
direction is along south of east at angle 64.62° , anticlockwise
total travel 345 feet
Explanation:
given data
walk east = 111 feet
walk south = 234 feet
to find out
How far did the pirate walk and displacement vector and distance and direction relative to east
solution
we consider here distance AB is 111 feet and than he turn right i.e south distance BC is 234 feet so
so angle BAC will be
tan θ =
θ = 64.62
and AC distance will be
AC =
AC = 259 feet
so pirate walk 259 feet
and
displacement vector is express as
displacement vector = AC ( cosθ i + sinθ j )
displacement vector = 259 ( cos64.62 i + sin64.62 j )
displacement vector = 111 i - 234 j
and
so direction is along south of east at angle 64.62° , anticlockwise
