Answer:
Center of mass lies 24 m in front of center of mass of second wagon.
Explanation:
Suppose A 1200 kg station wagon is moving along a straight highway at 12.0 m/s. Another car with mass 1800 kg and speed 20.0 m/s.
Given that,
Mass of first wagon = 1200 kg
Mass of second wagon = 180 kg
Distance = 40 m
We need to calculate the position of the center of mass of the system
Using formula of center mass



Hence, Center of mass lies 24 m in front of center of mass of second wagon.
Answer:
Momentum of the bowling pin is 17kgm/s
Explanation:
P(initial of ball)=+30 kg m/s
P(initial of pin)=0 because its velocity is 0
P initial = P final
30= P(ball) + P(pin)
30=13+P(pin)
P(final of pin)=+13 kg m/s and P(final of ball)= 30-13=17kgm/s
