Which of the following is the correct description of momentum? -the product of mass and acceleration -the product of mass and velocity
-velocity divided by mass
-acceleration divided by mass​

The product of mass and velocity is the correct answer

Explanation:

Momentum is defined as mass × velocity

p = mv

which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving?  

answer

a 75kg dining table

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
