Answer:
The speed of the two cars after coupling is 0.46 m/s.
Explanation:
It is given that,
Mass of car 1, m₁ = 15,000 kg
Mass of car 2, m₂ = 50,000 kg
Speed of car 1, u₁ = 2 m/s
Initial speed of car 2, u₂ = 0
Let V is the speed of the two cars after coupling. It is the case of inelastic collision. Applying the conservation of momentum as :
V = 0.46 m/s
So, the speed of the two cars after coupling is 0.46 m/s. Hence, this is the required solution.
Answer:
Explanation:
Using the Law of Conservation of Momentum, we can set up the following equation:
, where 
is Bruce's momentum and 
.
Plugging in given values, we get:
.
The ball would move about, 674 kilometers. I think I’m correct. Somebody correct me if I’m not.
Answer:
The distance is 1.026 m.
Explanation:
mass of rod, M = 1.23 kg
Length, L = 1.25 m
mass, m = 10 kg
Time period, T = 2 s
Let the distance is d.
The formula of the time period is given by
Answer: a) close together
Explanation: The electric field lines also represent the intensity of the field, in this sense for strong electric fields it is usually draw the lines close to each other. In constrast when they are far apart the electric field is weak.
