The first and third choices could both do it, but the first choice makes a much better, clear demonstration.
Follow stop drop and roll if the fire is in the room
Other wise exit immediately and find the nearest fire point. Then when you are out phone the fire services.
I hope this helps :)
Answer: I am pretty sure it is (b) what is the value of mass suspended at the end of the spring.
Explanation:
Answer:
100kg
Explanation:
Total force =400N+600N=1000N
As we have,
F=m×g
1000N=m×10m/s²
1000N÷10m/s²=m
m=100kg
To solve this problem it is necessary to apply the equations related to the conservation of momentum. Mathematically this can be expressed as

Where,
= Mass of each object
= Initial velocity of each object
= Final Velocity
Since the receiver's body is static for the initial velocity we have that the equation would become



Therefore the velocity right after catching the ball is 0.0975m/s
