What is the momentum of a child and a wagon if the total mass of the child and wagon is 22kg and the velocity is 1.5m/s?

33 kg m/s

Explanation:

The momentum of an object is given by:

where

m is the mass of the object

v is the velocity of the object

In this problem, the total mass of the child and the wagon is m =22 kg, while the velocity is v = 1.5 m/s, therefore the momentum is

find the surface area of the sphere to the nearest square unit. use a calculator.

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
