 (33 points) In the problem below, the velocity of the boat,
v_{b}, is 15 m/s. The velocity of the current,
v_{c} is 5 m/s. The width of the river is 125
m.
 How long does it take the boat to reach the
other side of the river?
 How far does the boat move horizontally along the river
in this time. (What is the horizontal distance from where the
boat starts to the large X?)
 With what total (resultant) speed does the is boat
move?
 (33 points) In the figure below, a ball rolls off of a table
horizontally with a speed of 3.6 m/s. The table is 1.54 m
tall. Use 9.8 m/s^{2} for the acceleration
of gravity (g).
 How long does it take for the ball to reach
the ground?
 How far away from the table (horizontally) does it
land?
 How fast is the ball moving when it hits the
ground?
 (33 points) A football punter kicks a ball at an angle of
72° with a speed of 15 m/s.
 How far down the field does the ball
travel?
 What is the maximum height reached by the
ball?
 How long is the ball in the air?
