How do you determine velocity

WebDisplacement Δ x is the change in position of an object: Δ x = x f − x 0, 3.1. where Δ x is displacement, x f is the final position, and x 0 is the initial position. We use the uppercase Greek letter delta (Δ) to mean “change in” whatever quantity follows it; thus, Δ x means change in position (final position less initial position). WebMar 26, 2016 · you explain, is the momentum of the bullet: pi = mvi. Because the bullet sticks in the wooden block, the final momentum is the product of the total mass, m1 + m2, and the final velocity of the bullet/wooden block combination: pf = ( m1 + m2) vf. Because of the principle of conservation of momentum, you can say that. pf = pi.
