Question

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

Answer 1

Answer:

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
