A 8.0 N force acts on a 0.30-kg object for 0.20 seconds. By how much does the object's momentum change (in kg-m/s)? (NEVER include units in the answer to a numerical question.)

Respuesta :

Answer:

The change in momentum of an object is 1.6 kg-m/s.  

Explanation:

It is given that,

Mass of the object, m = 0.3 kg

Force acting on it, F = 8 N

Time taken, t = 0.2 s

We need to find the change in momentum of an object. The change in momentum is equal to the impulse imparted on an object i.e.

[tex]\Delta p=J=F.\Delta t[/tex]

[tex]\Delta p=8\ N\times 0.2\ s[/tex]

[tex]\Delta p=1.6\ kg-m/s[/tex]

So, the change in momentum of an object is 1.6 kg-m/s. Hence, this is the required solution.

The change in the momentum of the object is 1.6 kg-m/s.

What is change in momentum?

Change in momentum is the product of force acting on a body and time

To calculate the change in momentum of the object, we use the formula below

Formula:

  • ΔM = Ft...............Equation 1

Where:

  • ΔM = change in momentum of the object
  • m = Force acting on the object
  • t = time.

From the question,

Given:

  • F = 8 N
  • t = 0.20 seconds

Substitute these values into equation 1

  • ΔM = (8×0.2)
  • ΔM = 1.6 kg-m/s

Hence, The change in the momentum of the object is 1.6 kg-m/s.
