Answer:
<em>conservation of momentum and energy using a series of swinging spheres</em>
Answer:
The speed of the car when load is dropped in it is 10.90 m/s.
Explanation:
Given that,
Mass of the railroad car, m₁ = 11600kg
Mass of the load, m₂ = 5420kg
It can be assumed as the speed of the car, u₁ = 16 m/s
Initially, it is at rest, u₂ = 0
The additional load is dropped onto the car.
Let v is the speed of the car. It can be calculated using the conservation of momentum as :
So, the speed of the car when load is dropped in it is 10.90 m/s.

Answer:
need the points my bad bro
Explanation:
Answer:
D. 100 J
Explanation:
Given
Mass (m) = 2 kg
Height (h) = 5 m
Acceleration due to gravity (g) = 10 m/s²
Now
Work done(W)
= m * g * h
= 2 * 10 * 5
= 100 Joule
Hope it will help :)❤
