1. The problem statement, all variables and given/known data A 15000 kg train traveling at 30m/s collides with a 2500 truck with a 90 kg man going at 22m/s in the opposite direction. The time of collision is 1.5 seconds. After collision, both objects are moving in the same direction with a velocity of 22 m/s. What is the size of the force felt by the man 2. Relevant equations ft=mΔv f=ma 3. The attempt at a solution I tried to use the impulse equation, but can't seem to get a reasonable answer from it. I tried to find the acceleration then the next force, but still couldn't find a reasonable answer for the force. I first tried to find acceleration using Vf=Vi+at. 22=-22+1.5a a=29.2 m/s/s f=90*29.2 f=2640 N that force seems to small for a collision like this. would it be reasonable to assume the force felt by the car is about equal to what the person will feel?
