1. Some jerk throws a 0.2 kg snowball at your head so
that it is travelling 10 m/s right before it collides with your
head. When the snowball hits your 5kg head, it bounces off and
travels to the left at 0.5 m/s. Using conservation of momentum,
determine the speed of your head after the snowball collides with
it.
2. Cart A (0.200 kg) is moving to the right at 0.34 m/s.
Cart B is stationary. Cart A collides into Cart B. The two carts
stick together and move to the right at 0.12 m/s. Determine the
mass of Cart B.
3. Cart A (0.200 kg) is moving to the right at 0.34
m/s. Cart B (0.400 kg) is stationary. Cart A collides into Cart B.
After the collision, Cart A moves to the left at 0.112 m/s.
Determine the velocity of Cart B after the collision?
4. Cart A (0.400 kg) is moving to the right at 0.34
m/s. Cart A collides into Cart B (0.200 kg). After the collision,
Cart A moves to the left at 0.1417 m/s and Cart B moves right at
0.397 m/s. Determine the velocity of Cart B before the
collision.
5. Cart A is moving to the right at 0.34 m/s. Cart
B (0.325 kg) is stationary. Cart A collides into Cart B. After the
collision, Cart A moves to the left at 0.112 m/s and Cart B moves
right at 0.227 m/s. Determine the mass of Cart A.
