Hi
Let the North be represented by Y-axis. The
when the car turns left, it moves along the -ve
x-axis, towards West.
Let
vl =50j kmph and, v2 = —50i kmph
Change in velocity is =
v2—vl = —50i — 507 kmph
Magnitude of change in velocity is
/507 + 50? = 50/2
The direction of the change in velocity =
Southwest, 45 deg. from South towards West.
