A8.0 n force acts on a 0.70-kg object for 0.50 seconds. by how much does the object's momentum change (in kg-m/s)? (never include units in the answer to a numerical question.)

Given the force acting on the object, the change in its momentum is 4kg.m/s.

To determine the object's change in momentum, we use the Impulse Momentum Theorem:

The impulse applied to a body or matter is equal to the change in its momentum

Impulse = Change in Momentum

Where F is the force applied and is the elapsed time

Hence

We substitute our given values into the equation

Therefore, given the force acting on the object, the change in its momentum is 4kg.m/s.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
