Impulse and momentum / work-energy
Hello, I am wondering why this take at a solution is wrong. So basically, $F = \frac{dp}{dt} \Rightarrow F = m\frac{dv}{dt} \Rightarrow F_{\text{avg}}\Delta t = m \Delta v$. Quick conversions show that 70 km/hr = 19.4 m/s, and therefore $\Delta t = \frac{0.94}{19.4} = 0.04845$. Therefore, the...- GoonP
