A steel ball whose mass is 2.0 kg is rolling at a rate of 2.8 m/s. What is its momentum? 1) 1.4 kgm/s

2) .71 kgm/s

3) 5.6 kgm/s

4) 4.8 kgm/s

mxv

Step-by-step explanation:

2.0x2.8=5.6

momentums equation is mass times velocity so 2.0kg is the mass and you multiply it by the velocity which is 2.8m/s and that is how you get your answer. your answer is number 3

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
