Question
![A football field is covered with frictionless ice.
A 90.0 kg player is skating down the field with a constant velocity v= 4.01i + 3.0j m/s. A
400 g football is thrown towards the player with a straight, horizontal pass. The velocity
of the football the moment before it reaches the player's hands is v= 20.0i + 15.0j m/s.
The player catches the ball and the two slide along the ice with a final velocity vf.
(a) Find the final velocity, of, of the player holding the ball. Write the velocity vector in
component form (e.g., À = Axi+ Ayj). Report your answer to two decimal places.
(b) Find the change in kinetic energy of the player + football system. Round your answer
to the nearest integer.
Note: the x and y directions are in the horizontal plane, as shown below. The x-direction
points along the length of the field and the y-direction points along the width of the
field. The player and ball do not travel in the vertical direction.
