Suppose that a second penguin with a mass of 4kg sliding on the same frictionless ice hits the same snow patch. This
Denguin has an initial velocity of 3m/s when it hits the snow patch. Over 2 seconds, it slows down to Om/s. Based on this
nformation, what is the impulse of this penguin?
What is the force of friction which slowed this penguin down?
a. J=6kgm/s; F=12N
b. J=3kgm/s^2; F=6N
c. 12kgm/s; F=24N
d. J=12kgm/s; F=6N
