1. A bicycle has a momentum of 30kgm/s what momentum would the bicycle have if it had
A.twice the mass and was moving at the same speed ?


b.the same mass and was moving of twice the speed ?


C.one half the mass and was moving twice the speed ?


D.the same mass and was moving 0.5 the speed ?


E.three time the mass and was moving with 0.5 the speed


F.thrice the mass and was moving twice the speed

2. A 72kg boy and a 48kg girl both wearing ice skates face each other at rest on a skating rink. The boy pushes the girl sending her eastward with a speed of 6.8m/s
When the impulse is completed the boy and girl are a distance of 1.4m apart .

Determine the distance of separation between them at 5.0 sec after the impulse is completed.

Use the linear momentum relationship from Newton's second law of motion and apply simple variation you get the results of A to F in Quest 1
