a mass has 2.0x10^3kg and a metal bar has a mass of 400kg. the object strikes the bar at a speed of 6.0 ms^-1 it comes to rest on the bar without bouncing. as a result of the collision, the bar is driven into the ground to a depth of 0.75m. determine the speed of the bar immediately after the object strikes it.
i have no clue lol
also how do you determine the average frictional force exerted by the ground on the bar?
