2021 CAIE AS & A level May June Physics Paper 12 Q. No. 10 (9702/12/M/J/21) by Sajit Chandra Shakya from Nepal
Chapter - DYNAMICS
A nitrogen molecule P travelling at a speed of 320 m s–1 in a vacuum collides with a stationary
nitrogen molecule Q.
After the collision, P travels at a velocity of 180 m s–1 at an angle of 55 to its original path.
Q travels in a direction at an angle of 34 to the initial path of P
Assume that there are no external forces acting on the molecules.
What is the magnitude v of the velocity of Q after the collision?
A 120 m s–1 B 140 m s–1 C 180 m s–1 D 260 m s–1
