Question

An elastic collision occurs between two air hockey pucks inwhich one puck is at rest and the other is moving with a speed of0.6 m/s. After the collision, the puck initially in motion makes anangle of 35.00 o with its original direction, and thestruck puck moves at an angle of 55.00 o on the otherside of the original direction. What is the final speed of thefirst puck? What is the final speed of the second?

Explanation / Answer

along X axis m*0.6=m*cos35-m*v*cos55 along Y direction 0=m*sin35-m*v*sin55 solving we will get the answer.
