If you lived downhill and lave started to flow toward your home sometime that could happen is the lava could completely demolish your home
Answer:
The original speed of the mess kit is 5.65 m/s.
Explanation:
Given that,
Mass of kit =7.0 kg
Mass of first = 3.5 kg
Speed= 5.5 m/s
Speed of other particle part = 7.5 m/s
Angle = 30°
We need to calculate the momentum of first part
Using formula of momentum
Put the value into the formula
We need to calculate the momentum of second part
Using formula of momentum
We need to calculate the total momentum
We need to calculate the original speed of the mess kit
Using formula of momentum
Put the value into the formula
Hence, The original speed of the mess kit is 5.65 m/s.
The greater mass the object has the greater its inertia would be. As inertia becomes greater, the same happens with the force which is needed stop motion. Linear motion and rotational motion are quite different, because the first one depends only on mass while the second embraces mass, size and shape of an object. According to the information I shared, one will not be able to stop 10 kg mass due to far greater inertia than object of 1kg mass.
Hope you will find it helpful.
