Question

Timmy is given a set of questions relating to his winter vacation. Answer the following two-part question: You walk on top of a long sled that Is free to move on an lcy (frictionless) horizontal road. The sled does not move while you are walking The sled ceases to move once you obtain a constant speed. The sled moves with velocity opposite to your velocity. The sled moves with a momentum opposite to your momentum A person with a mass of 50 kg is riding on a merry-go-round. If the person has a speed of 3 m/s and is located 2 m from of the merry-go-round, what is the person's angular momentum 100 kg m^2/s 150 kg m^2/s 300 kg m^2/s 900 kg m^2/s

Explanation / Answer

1a.

here , as the ice is frictionless , there will be no force acting on the sled ,hence, the centre of mass will stay at the same position

hence , the sled will have equal and oposite momentum to your momentum

part d) the sled moved with momentum opostie to your momentum

1b)

mass , m = 50 Kg

v =3 m/s

d = 2 m

angular momentum pf person = m * v * d

angular momentum pf person = 50 * 2 * 3

angular momentum pf person = 300 Kg.m^2/s
