retarding force impacting a stationary object
Please can you check and if i have gone wrong tell me?
1. The problem statement, all variables and given/known data
A mass of 150 kg is dropped onto a pile of mass 1,200kg from a height of 2.5m and drives it 7cm into the ground. calculate (a) the intial velocity of pile and driving weight immediately after impact, (b) the average reisting force exerted by the ground.
2. Relevant equations
3. The attempt at a solution
Here is my attempt not the best.
Intial velocity of pile and driving weight after impact
(a)v=3.8m/s combired velocity after impact
V=0m/s combined mass
