What is the velocity of v2 if m1=82kg v1= 25 m/s m2=60kg?

Given :

Let, us assume that momentum is conserved during the process.

To Find :

The velocity .

Solution :

Applying conservation of momentum :

Initial momentum = Final momentum

Hence, this is the required solution.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
