a 10kg cement block horizontally at 6 m/s plows into a bank of sand and comes to a stop in 2.0 m/s. What is the average impact force on the bank?

Respuesta :

I assume the block plows into the bank of sand with a velocity of 6 m/s and comes to a stop in 2 s.

[tex] \bar Ft = \Delta mv \\ \\ \bar F = \frac{\Delta mv }{t} \\ \\ \bar F \ avarage \ Force \\ m \ momentum \\ v \ velocity \\ t \ time[/tex]
