Explanation Given data: Mass of the ant ( m ) is 12 mg, which is 12 × 10 − 6 kg . The average force applied by the ant ( F avg ) is 47 mN . The time duration at which the ant applied the force on mandibles Δ t is 0.13 ms. From the given data, the initial velocity of the ant ( v i ) is 0 m s . It is required to find the final velocity of the ant. Formula used: Write the expression for average force ( F a v g ) applied by the ant on the mandibles as follows. F a v g = Δ p Δ t (1) Here, Δ p is the change in the momentum of the ant, and Δ t is the time duration, which is 0.13 ms. Write the expression for change in momentum of the ant in terms of velocity and mass. Δ p = m ( v f − v i ) (2) Here, m is the mass of the ant, v f is the final velocity of the ant, and v i is the initial velocity of the ant. Explanation: Calculation of final velocity of the ant ( v f ) : From equation (2), substitute [ m ( v f − v i ) ] for Δ p in equation (1), F a v g = m ( v f − v i ) Δ t Rearrange the expression to find the final velocity of the ant as follows. v f = F a v g ( Δ t ) m + v i Substitute 12 × 10 − 6 kg for m , 47 mN for F avg , 0
