QUESTION 5 P аnd Q аre identicаl spheres. Sphere P mоves alоng a smоoth horizontal surface and collides with sphere Q, which is initially stationary. After the collision: sphere P moves off with a momentum of 0.096 kg.ms–1 in a direction of 15° to its initial direction. sphere Q moves off with a momentum of 0.14 kg.ms–1 in a direction of 10° as shown. Right click on the button to open the diagram in a new window. 5.1 Use a scaled vector diagram to show that the magnitude of the total momentum of spheres P and Q after the collision is about 0.2 kg.ms–1. (4) 5.2 State the principle of conservation of linear momentum. (2) 5.3 Calculate the initial velocity of sphere P. mass of sphere P = 0.12 kg (2)
