The 450 kg ram of a pile driver falls 1.4 m from rest and strikes the top of a 240 kg pike embedded 0.9 m in the ground. Upon impact, the ram is seen to move with the pile with no appreciable rebound. Determine the velocity v of the ram and pile. 1.4 m 0.9 m We can draw out separate FBDs like we did for the car problem, or recognize that the impact will result in a conservation of linear momentum (as long as we assume mg is small compared to the impact force). What is the velocity of the ram when it hits the pile? T1+ V1e+ V1g+ U1-2= T2+ V2e+ V2g Set datum at top of pile mgh = ½mv2
