A sphere travelling at speed v collides elastically with an identical sphere which is at rest.

After the collision, both spheres move off at an angle θ to the direction of travel of the first sphere, as shown. The spheres have the same speed as each other.

q7-wph14-04-june-2021-edexcel-int-as-and-a-level-phy

What is the speed of the spheres after the collision?

  • v

  • fraction numerator v over denominator square root of 2 end fraction

  • v over 2

  • v over 4
