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

Choice D

The velocity is Option D. -10 m/s

What is velocity?

  • Velocity is the speed at which something moves in the same direction.
  • For example, the speed of a car traveling north on a highway, or the speed a rocket travels after launching.
  • Velocity is defined as the displacement of an object in a unit of time.
  • The formula of velocity is

v = p/m

v = velocity

p = momentum

m = mass of the object

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

p = mv

p is its momentum, m exists its mass, and v stands for its velocity.

Given values:

p = -80kg×m/s

m = 8kg

Plug in these values and solve for v:

-80 = 8v

v = -10m/s

  • The SI unit of velocity is m/s.
  • Velocity is also defined as the rate of change of displacement of the body with respect to time.

The velocity is Option D. -10 m/s
