What is the momentum of a #400"kg"# object moving with velocity #8"m"//"s"#?

Answer 1

Isabella Alvarez

#p=3200 (kgm)/s#

Momentum, #vecp#, is given by the product of an object's mass, #m#, and velocity, #vecv#.

#vecp=mvecv#

With a mass of 400 kg and a speed of 8 m/s,

#p=(400kg)(8m/s)#

#=>p=3200(kgm)/s#

Because we haven't indicated a direction, momentum is a vector quantity, so our calculated value is a magnitude.

The momentum of a 400 kg object moving with a velocity of 8 m/s is 3200 kg*m/s.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
