An aircraft heading due west at 48 m/s encounters a wind blowing towards the south at 27
m/s. What is the resultant velocity (speed and direction) of the aircraft?
6.
A boat is headed directly across a river at 7.8 m/s due north, while the river’s current travels
at 3.2 m/s due east. All speeds are relative to a point on shore.
a) What is the velocity of the boat (speed and direction) relative to shore?
b) If the river is 820 m wide, how far downstream does the boat end up, once across?

An jet aircraft is travelling 310 m/s at 35 south of east. What is the south component of its
velocity?
9.
An arrow is shot at 35 m/s into the air at an angle of 400 to the horizontal. Determine the vertical
and horizontal components of its speed.

Three physics students are fighting over a graphing calculator. Student A pulls on the
calculator with a force of 15 N north, while student B pulls with a 35 N force east. What force,
and in what direction, must student C apply to the calculator if it is to remain stationary (i.e.
the net force = 0)?
