If the mass of an object is 8 kg and its momentum is - 80 kgm/s, what is its velocity?

A. 10 m/s

B. 12 m/s

C. 8 m/s

D. - 10 m/s

An object's momentum is the product of its mass and its velocity:

p = mv

p is its momentum, m is its mass, and v is its velocity.

Given values:

p = - 80kg*m/s

m = 8kg

Plug in these values and solve for v:

-80 = 8v

v = - 10m/s
