Answer:
DL = 0.0105 [m] = 10.57 [mm]
Explanation:
To solve this problem, we use the following equation that involves length changes depending on temperature changes.
where:
DL = length change
α = thermal expansion coefficient = 11 * 10^(-6) [1/°C]
DT = temperature change = (37-6) = 31 [°C]
L = nominal or initial length = 31 [m]
DL = 11 * 10^(-6) * 31 * 31
DL = 0.0105 [m] = 10.57 [mm]

Answer:
The speed of the large cart after collision is 0.301 m/s.
Explanation:
Given that,
Mass of the cart,
Initial speed of the cart,
Mass of the larger cart,
Initial speed of the larger cart,
After the collision,
Final speed of the smaller cart, (as its recolis)
To find,
The speed of the large cart after collision.
Solution,
Let is the speed of the large cart after collision. It can be calculated using conservation of momentum as :
So, the speed of the large cart after collision is 0.301 m/s.
