Question
Is it generally a good idea to gain understanding of the 'size' of units. Consider the following objects and calculate the magnitude of their momentum in SI units.A) A ladybug weighing 36.20 milligram flies by your head at 2.69 mph. [Find this answer in kg•m/s]
B) A 66.40-lb boy walks at 2.55 mph [Find this answer in kg•m/s]
C) A car weighing 2164 lbs is moving at a speed of 31.30 mph. [Find this answer in kg•m/s]

Explanation / Answer
Solution:
A)
m = 36.20 milligram = 3.62*10-5 kg
and
v = 2.69 miles/hour = 1.2025 metre/sec
hence;
P = mv = 4.353*10-5 kg-m/s
B)
Here;
m= 66.4-lb = 30.118 kg
and
v = 2.55 mph = 1.139 m/s
hence;
P = 34.3044 kg-m/s
C)
Here;
m= 2164 lbs = 981.57 kg
and
v = 31.30 mph = 13.99 m/s
hence;
P = mv = 13,732.1643 kg-m/s
