At a carnival game, two balls are Identical in
mass and radius, but one is made of steel and
one is made of rubber. The game is to throw
them at a bowling pin and try to knock it over.
If the balls are thrown with the same speed
and hit the same spot on the bowling pin,
which Is more likely to knock it over?
A. The steel ball
B. Without knowing more information, this
cannot be answered.
C. Both are equally likely since they have the
same momentum
D. The rubber ball
You're rolling solid rubber balls on the kitchen floor. Ball 1 has a density of 1.16 × 103 kg/m3 and a radius of 28.0 mm. Ball 2 has an unknown density and a radius of 43.0 mm and is initially at rest. You roll ball 1 at an initial speed of 3.00 m/s, and the two balls collide head-on. Ball 1 reverses direction and comes back to you at 2.00 m/s, and after the collision, the speed of ball 2 is 1.00 m/s. The positive x axis is in the direction of ball 1's initial motion.
