<em>The change of momentum of the dart is 0.84 Nw.s</em>
Explanation:
<u>Impulse and change of momentum</u>
The change in momentum of an object is its mass times the change in its velocity:
The change in the momentum can also be found by considering the force acting on it. If a force F acts for a time Δt, the change of momentum is given by:
The dart hits a dashboard with a net force of 14 N during the collision and stops in 0.06 seconds. The change of momentum is:
The change of momentum of the dart is 0.84 Nw.s
NaCl is a compound formed by a chemical reaction between Na (Sodium) and Cl (Chlorine). Sodium is an alkai metal in Group One of the Periodic Table, and it is very reactive.
