Answer:
To identify the momentum of object 1, you must multiply mass (m) and velocity(v) to find momentum.
Object 1 has momentum of 8 kg. m/s before collision.
Object 1 has momentum of 0 kg. m/s before collision.
The combined mass after the collision had a total momentum of 8 kg. m/s.
Explanation:
Momentum of the object is given by,
Momentum = mass × velocity
For object 1:
Momentum = mass × velocity
Momentum = 2 × 4
Momentum = 8 kg. m/s
For object 2:
Momentum = mass × velocity
Momentum = 6 × 0
Momentum = 0 kg. m/s
For object 1 + object 2:
Momentum = mass × velocity
Momentum = 8 × 1
Momentum = 8 kg. m/s
To identify the momentum of object 1, you must multiply mass (m) and velocity(v) to find momentum.
Object 1 has momentum of 8 kg. m/s before collision.
Object 1 has momentum of 0 kg. m/s before collision.
The combined mass after the collision had a total momentum of 8 kg. m/s.
Answer:
W = 750 [J]
Explanation:
The question should be related to work, work in physics is defined as the product of force by distance. In this way, we can use the following equation.
where:
F = force = 30 [N]
d = distance = 25 [m]
W = work [J]
Now replacing:
![W=30*25\\W=750 [J]](https://tex.z-dn.net/?f=W%3D30%2A25%5C%5CW%3D750%20%5BJ%5D)
In an attempt to reduce our dependence on non-renewable resources, and cut down on the harm to the environment, we could burn biomass to produce electricity.
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 :)
