Physics

A 0.21 kg hockey puck has a velocity of 2.2 m/s toward the east(the +x direction) as it slides over the frictionless surface of anice hockey rink. What are the:

(a) magnitude and (b) direction of the constant net force thatmust act on the puck during a 0.43 s time interval to change thepuck's velocity to 3.7 m/s toward the west?

and what are the:

(c) magnitude and (d) direction if, instead, the velocity ischanged to 3.7 m/s toward the south?
