What is the most accurate conceptual interpretation of impulse for a variable force?
A 4.04.0 kg cart receives an impulse of 18 N⋅s18\(\text{ N}\[\cdot\]\text{s}\) in the positive xx-direction. What is its change in velocity?
A launch assist force is modeled by F(t)=20t2F(t) = 20t^2 N. What is the impulse during the 1.51.5 s interval beginning 2.02.0 s after ignition?
