U1B also involved the study of momentum and impulse. This study involved 2 equations: \text { Equation } 1: \Delta p=p_{\text {final }}-p_{\text {initial }} \text { where delta }

\mathrm{p} \text { is impulse and } \mathrm{p} \text { is momentum } \text { Equation } 2: F t=\Delta p \text { where } \mathrm{F} \text { is the unbalanced force on the object and } \mathrm{t} \text { is the time the force is applied } 3) An unbalanced force of 4N is applied to a 2 kg object for 2.5 seconds. 3a) Would you use equation 1 or 2 to determine the impulse of the object? 3b) Use the equation you chose in 3a to determine the impulse. What is the final momentum of the object if the initial momentum was 1 kg*m/s
