The Impulse-momentum formula is obtained from the impulse-momentum theorem which states that change in momentum of an object is equal to impulse applied on the object. The formula is given as follows:
Impulse-momentum formula J=Δp
Solution
Given:
vi (Initial Velocity) = 12 m/s,
vf (Final Velocity) = -12m/s,
m (mass) = 0.15kg,
Find out
We have to determine the value of J (Impulse) = ?
Solution
Impulse is formulated as
J = mvf – mvi
= m(vf – vi)
On substituting the known values we get
= 0.15 Kg (-12 -12) m/s
J= -3.6N.
