Before a collision, a 50.0-kg object is moving at +5.0 m/s. find the impulse that acted on the object if, after the collision, it moves at +17.0 m/s.

J=600 kg m/s

Explanation:

Impulse And Momentum

Suppose a particle is moving at a certain speed and changes it to . The impulse J is equivalent to the change of linear momentum. The momentum can be computed by

The initial and final momentums are given, respectively, by:

Thus, the change of momentum is

It's equal to the Impulse J

Our data is

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
