A bean bag and a rubber ball are tossed against a wall. They both have a mass of 220 g and are thrown with an initial speed of 6.0 m/s. The rubber ball bounces back at the same speed it was travelling initially, but the bean bag stops when it hits the wall. The collision between the rubber ball and the wall takes 1/3 as long as the collision between the bean bag and the wall. You can treat this as only horizontal motion.

a. What is the impulse acting on the bean bag?
b. What is the impulse acting on the rubber ball?
c. Which object experiences the greater effective force from the wall? How do you know?
