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.
