Question

An object with a mass 4.0 kg has a momentum of 64 kgm/s . How fast is the object traveling ?

Answer 1

The object will travel at the speed of 16 m/s.

Step-by-step explanation:

Given

• Mass m = 4.0 kg

• Momentum p = 64 kgm/s

To determine

How fast is the object traveling?

Important Tip:

The product of the mass and velocity of an object — momentum.

Using the formula

`p = mv`

where

• m = mass

• v = velcity

• p = momentum

Thus, in order to determine the speed of the object, all we need to do is to substitute p = 64 and m = 4 in the formula

`p = mv`

`64\:=\:4* v`

switch the equation

`\:4* \:v\:=64`

divide both sides by 4

`(4v)/(4)=(64)/(4)`

simplify

`v=16` m/s

Therefore, the object will travel at the speed of 16 m/s.
