Question

According to Newton's Brd Law, an object's momentum depends on it's velocity and mass, 4 dog-sled teams

Answer 1

Answer:

Team A has the greatest momentum

Explanation:

The momentum of an object is a vector quantity given by

$p=mv$

where

m is the mass of the object

v is its velocity

In this problem, we have to compare the momenta of the different sleds.

We have:

A) Sled Team A 48 kg moving at 10m/s:

m = 48 kg

v = 10 m/s

p = (48)(10) = 480 kg m/s

B) Sled Team B 14 kg moving at 18m/s

m = 14 kg

v = 18 m/s

p = (14)(18) = 252 kg m/s

C) Sled Team C 28 kg moving at 12m/s

m = 28 kg

v = 12 m/s

p = (28)(12) = 336 kg m/s

D) Sled Team D 22 kg moving at 12m/s

m = 22 kg

v = 12 m/s

p = (22)(12) = 264 kg m/s

So, team A has the greatest momentum.
