Please hurry!!!

A bullet has a momentum of 3.2 kg*m/s. What is it to mass if it is traveling at 762 m/s?

A.) 42 kg
B.) 0.042 kg
C.) 42 ounces
D.) 0.000042 pounds

Answer 1

First we need to know the equation which is P=mv
Use the formula- 3.2 kg x m/s = 762 x V
divide 762 in both side to get the v by itself
now we will have 0.004193971166 and lets round it!
then we will have the answer of .0042
